description
The TLC271 operational amplifier combines a
wide range of input offset voltage grades with low
NC – No internal connection
offset voltage drift and high input impedance. In
addition, the TLC271 offers a bias-select mode
that allows the user to select the best combination of power dissipation and ac performance for a particular
application. These devices use Texas Instruments silicon-gate LinCMOS technology, which provides offset
voltage stability far exceeding the stability available with conventional metal-gate processes.

description (continued)
Using the bias-select option, these cost-effective devices can be programmed to span a wide range of
applications that previously required BiFET, NFET or bipolar technology. Three offset voltage grades are
available (C-suffix and I-suffix types), ranging from the low-cost TLC271 (10 mV) to the TLC271B (2 mV)
low-offset version. The extremely high input impedance and low bias currents, in conjunction with good
common-mode rejection and supply voltage rejection, make these devices a good choice for new
state-of-the-art designs as well as for upgrading existing designs.
In general, many features associated with bipolar technology are available in LinCMOS operational amplifiers,
without the power penalties of bipolar technology. General applications such as transducer interfacing, analog
calculations, amplifier blocks, active filters, and signal buffering are all easily designed with the TLC271. The
devices also exhibit low-voltage single-supply operation, making them ideally suited for remote and
inaccessible battery-powered applications. The common-mode input voltage range includes the negative rail.
A wide range of packaging options is available, including small-outline and chip-carrier versions for high-density
system applications.
The device inputs and output are designed to withstand – 100-mA surge currents without sustaining latch-up.
The TLC271 incorporates internal ESD-protection circuits that prevent functional failures at voltages up to 2000
V as tested under MIL-STD-883C, Method 3015.2; however, care should be exercised in handling these devices
as exposure to ESD may result in the degradation of the device parametric performance.
The C-suffix devices are characterized for operation from 0°C to 70°C. The I-suffix devices are characterized
for operation from – 40°C to 85°C. The M-suffix devices are characterized for operation over the full military
temperature range of – 55°C to 125°C.
bias-select feature
The TLC271 offers a bias-select feature that allows the user to select any one of three bias levels depending
on the level of performance desired. The tradeoffs between bias levels involve ac performance and power
dissipation (see Table 1).

bias selection
Bias selection is achieved by connecting the bias select pin to one of three voltage levels (see Figure 1). For
medium-bias applications, it is recommended that the bias select pin be connected to the midpoint between the
supply rails. This procedure is simple in split-supply applications, since this point is ground. In single-supply
applications, the medium-bias mode necessitates using a voltage divider as indicated in Figure 1. The use of
large-value resistors in the voltage divider reduces the current drain of the divider from the supply line. However,
large-value resistors used in conjunction with a large-value capacitor require significant time to charge up to
the supply midpoint after the supply is switched on. A voltage other than the midpoint can be used if it is within
the voltages specified in Figure 1.

high-bias mode
In the high-bias mode, the TLC271 series features low offset voltage drift, high input impedance, and low noise.
Speed in this mode approaches that of BiFET devices but at only a fraction of the power dissipation. Unity-gain
bandwidth is typically greater than 1 MHz.
medium-bias mode
The TLC271 in the medium-bias mode features low offset voltage drift, high input impedance, and low noise.
Speed in this mode is similar to general-purpose bipolar devices but power dissipation is only a fraction of that
consumed by bipolar devices.

PARAMETER MEASUREMENT INFORMATION
single-supply versus split-supply test circuits
Because the TLC271 is optimized for single-supply operation, circuit configurations used for the various tests
often present some inconvenience since the input signal, in many cases, must be offset from ground. This
inconvenience can be avoided by testing the device with split supplies and the output load tied to the negative
rail. A comparison of single-supply versus split-supply test circuits is shown below. The use of either circuit gives
the same result.

PARAMETER MEASUREMENT INFORMATION
input bias current
Because of the high input impedance of the TLC271 operational amplifiers, attempts to measure the input bias current
can result in erroneous readings. The bias current at normal room ambient temperature is typically less than 1 pA,
a value that is easily exceeded by leakages on the test socket. Two suggestions are offered to avoid erroneous
measurements:
1. Isolate the device from other potential leakage sources. Use a grounded shield around and between the
device inputs (see Figure 101). Leakages that would otherwise flow to the inputs are shunted away.
2. Compensate for the leakage of the test socket by actually performing an input bias current test (using a
picoammeter) with no device in the test socket. The actual input bias current can then be calculated by
subtracting the open-socket leakage readings from the readings obtained with a device in the test socket.
One word of caution: many automatic testers as well as some bench-top operational amplifier testers us the
servo-loop technique with a resistor in series with the device input to measure the input bias current (the voltage drop
across the series resistor is measured and the bias current is calculated). This method requires that a device be
inserted into the test socket to obtain a correct reading; therefore, an open-socket reading is not feasible using this
method.

Figure 101. Isolation Metal Around Device inputs (JG and P packages)
low-level output voltage
To obtain low-supply-voltage operation, some compromise is necessary in the input stage. This compromise
results in the device low-level output being dependent on both the common-mode input voltage level as well
as the differential input voltage level. When attempting to correlate low-level output readings with those quoted
in the electrical specifications, these two conditions should be observed. If conditions other than these are to
be used, please refer to the Typical Characteristics section of this data sheet.
input offset voltage temperature coefficient
Erroneous readings often result from attempts to measure temperature coefficient of input offset voltage. This
parameter is actually a calculation using input offset voltage measurements obtained at two different
temperatures. When one (or both) of the temperatures is below freezing, moisture can collect on both the device
and the test socket. This moisture results in leakage and contact resistance which can cause erroneous input
offset voltage readings. The isolation techniques previously mentioned have no effect on the leakage since the
moisture also covers the isolation metal itself, thereby rendering it useless. It is suggested that these
measurements be performed at temperatures above freezing to minimize error.

PARAMETER MEASUREMENT INFORMATION
full-power response
Full-power response, the frequency above which the amplifier slew rate limits the output voltage swing, is often
specified two ways: full-linear response and full-peak response. The full-linear response is generally
measuredby monitoring the distortion level of the output while increasing the frequency of a sinusoidal input
signal until the maximum frequency is found above which the output contains significant distortion. The full-peak
response is defined as the maximum output frequency, without regard to distortion, above which full
peak-to-peak output swing cannot be maintained.
Because there is no industry-wide accepted value for significant distortion, the full-peak response is specified
in this data sheet and is measured using the circuit of Figure 98. The initial setup involves the use of a sinusoidal
input to determine the maximum peak-to-peak output of the device (the amplitude of the sinusoidal wave is
increased until clipping occurs). The sinusoidal wave is then replaced with a square wave of the same
amplitude. The frequency is then increased until the maximum peak-to-peak output can no longer be maintained
(Figure 102). A square wave is used to allow a more accurate determination of the point at which the maximum
peak-to-peak output is reached.

test time
Inadequate test time is a frequent problem, especially when testing CMOS devices in a high-volume,
short-test-time environment. Internal capacitances are inherently higher in CMOS than in bipolar and BiFET
devices, and require longer test times than their bipolar and BiFET counterparts. The problem becomes more
pronounced with reduced supply levels and lower temperatures.

While the TLC271 performs well using dual power
supplies (also called balanced or split supplies),
the design is optimized for single-supply
operation. This includes an input common mode
voltage range that encompasses ground as well
as an output voltage range that pulls down to
ground. The supply voltage range extends down
to 3 V (C-suffix types), thus allowing operation
with supply levels commonly available for TTL and
HCMOS; however, for maximum dynamic range,
16-V single-supply operation is recommended.

APPLICATION INFORMATION
single-supply operation (continued)
Many single-supply applications require that a voltage be applied to one input to establish a reference level that
is above ground. A resistive voltage divider is usually sufficient to establish this reference level (see Figure 103).
The low input bias current consumption of the TLC271 permits the use of very large resistive values to
implement the voltage divider, thus minimizing power consumption.
The TLC271 works well in conjunction with digital logic; however, when powering both linear devices and digital
logic from the same power supply, the following precautions are recommended:
1. Power the linear devices from separate bypassed supply lines (see Figure 104); otherwise, the linear
device supply rails can fluctuate due to voltage drops caused by high switching currents in the digital logic.
2. Use proper bypass techniques to reduce the probability of noise-induced errors. Single capacitive
decoupling is often adequate; however, RC decoupling may be necessary in high-frequency applications.

input offset voltage nulling
The TLC271 offers external input offset null control. Nulling of the input off set voltage may be achieved by
adjusting a 25-kΩ potentiometer connected between the offset null terminals with the wiper Connected as
shown in Figure 105. The amount of nulling range varies with the bias selection. In the high-bias mode, the
nulling range allows the maximum offset voltage specified to be trimmed to zero. In low-bias and medium-bias
modes, total nulling may not be possible.

bias selection
Bias selection is achieved by connecting the bias select pin to one of the three voltage levels (see Figure 106).
For medium-bias applications, R is recommended that the bias select pin be connected to the mid-point
between the supply rails. This is a simple procedure in split-supply applications, since this point is ground. In
single-supply applications, the medium-bias mode necessitates using a voltage divider as indicated. The use
of large-value resistors in the voltage divider reduces the current drain of the divider from the supply line.
However, large-value resistors used in conjunction with a large-value capacitor requires significant time to
charge up to the supply midpoint after the supply is switched on. A voltage other than the midpoint may be used
if it is within the voltages specified in the table of Figure 106.

input characteristics
The TLC271 is specified with a minimum and a maximum input voltage that, if exceeded at either input, could
cause the device to malfunction. Exceeding this specified range is a common problem, especially in
single-supply operation. Note that the lower range limit includes the negative rail, while the upper range limit
is specified at VDD – 1 V at TA = 25°C and at VDD – 1.5 V at all other temperatures.
The use of the polysilicon-gate process and the careful input circuit design gives the TLC271 very good input
offset voltage drift characteristics relative to conventional metal-gate processes. Offset voltage drift in CMOS
devices is highly influenced by threshold voltage shifts caused by polarization of the phosphorus dopant
implanted in the oxide. Placing the phosphorus dopant in a conductor (such as a polysilicon gate) alleviates the
polarization problem, thus reducing threshold voltage shifts by more than an order of magnitude. The offset
voltage drift with time has been calculated to be typically 0.1 µV/month, including the first month of operation.
Because of the extremely high input impedance and resulting low bias current requirements, the TLC271 is well
suited for low-level signal processing; however, leakage currents on printed circuit boards and sockets can
easily exceed bias current requirements and cause a degradation in device performance. It is good practice to
include guard rings around inputs (similar to those of Figure 101 in the Parameter Measurement Information
section). These guards should be driven from a low-impedance source at the same voltage level as the
common-mode input (see Figure 107).
The inputs of any unused amplifiers should be tied to ground to avoid possible oscillation.
noise performance
The noise specifications in operational amplifier circuits are greatly dependent on the current in the first-stage
differential amplifier. The low input bias current requirements of the TLC271 results in a very low noise current,
which is insignificant in most applications. This feature makes the devices especially favorable over bipolar
devices when using values of circuit impedance greater than 50 kΩ, since bipolar devices exhibit greater noise
currents.

Operational amplifier circuits almost always
employ feedback, and since feedback is the first
prerequisite for oscillation, a little caution is
appropriate. Most oscillation problems result from
driving capacitive loads and ignoring stray input
capacitance. A small-value capacitor connected
in parallel with the feedback resistor is an effective
remedy (see Figure 108). The value of this
capacitor is optimized empirically.
Figure 108. Compensation for Input
Capacitance
electrostatic discharge protection
The TLC271 incorporates an internal electrostatic-discharge (ESD) protection circuit that prevents functional
failures at voltages up to 2000 V as tested under MIL-STD-883C, Method 3015.2. Care should be exercised,
however, when handling these devices as exposure to ESD may result in the degradation of the device
parametric performance. The protection circuit also causes the input bias currents to be temperature dependent
and have the characteristics of a reverse-biased diode.
latch-up
Because CMOS devices are susceptible to latch-up due to their inherent parasitic thyristors, the TLC271 inputs
and output were designed to withstand – 100-mA surge currents without sustaining latchup; however,
techniques should be used to reduce the chance of latch-up whenever possible. Internal protection diodes
should not by design be forward biased. Applied input and output voltage should not exceed the supply voltage
by more than 300 mV. Care should be exercised when using capacitive coupling on pulse generators. Supply
transients should be shunted by the use of decoupling capacitors (0.1 µF typical) located across the supply rails
as close to the device as possible.
The current path established if latch-up occurs is usually between the positive supply rail and ground and can
be triggered by surges on the supply lines and/or voltages on either the output or inputs that exceed the supply
voltage. Once latch-up occurs, the current flow is limited only by the impedance of the power supply and the
forward resistance of the parasitic thyristor and usually results in the destruction of the device. The chance of
latch-up occurring increases with increasing temperature and supply voltages.

All operating characteristics of the TLC271 were
measured using a 20-pF load. The devices drive
higher capacitive loads; however, as output load
capacitance increases, the resulting response
pole occurs at lower frequencies, thereby causing
ringing, peaking, or even oscillation (see Figures
110, 111, and 112). In many cases, adding some
compensation in the form of a series resistor in the
feedback loop alleviates the problem.

The output stage of the TLC271 is designed to
sink and source relatively high amounts of current
(see Typical Characteristics). If the output is
subjected to a short-circuit condition, this high
current capability can cause device damage
under certain conditions. Output current capability
increases with supply voltage.

Although the TLC271 possesses excellent high-level output voltage and current capability, methods are
available for boosting this capability, if needed. The simplest method involves the use of a pullup resistor (RP)
connected from the output to the positive supply rail (see Figure 113). There are two disadvantages to the use
of this circuit. First, the NMOS pulldown transistor, N4 (see equivalent schematic) must sink a comparatively
large amount of current. In this circuit, N4 behaves like a linear resistor with an on-resistance between
approximately 60 Ω and 180 Ω, depending on how hard the operational amplifier input is driven. With very low
values of RP, a voltage offset from 0 V at the output occurs. Secondly, pullup resistor RP acts as a drain load
to N4 and the gain of the operational amplifier is reduced at output voltage levels where N5 is not supplying the
output current.
