ThinSOT is a trademark of Linear Technology Corporation.
The LT®1803/LT1804/LT1805 are single/dual/quad, low
power, high speed rail-to-rail input and output operational
amplifiers with excellent DC performance. The LT1803/
LT1804/LT1805 feature reduced supply current, lower
input offset voltage, lower input bias current and higher
DC gain than other devices with comparable bandwidth
and slew rate.
Typically, the LT1803/LT1804/LT1805 have an input offset voltage of 350µV, an input bias current of 125nA and
an open-loop gain of 60V/mV.
The LT1803/LT1804/LT1805 have an input range that
includes both supply rails and an output that swings within
20mV of either supply rail to maximize the signal dynamic
range in low supply applications.
The LT1803/LT1804/LT1805 are specified at 3V, 5V and
±5V supplies and typically maintain their performance for
supplies from 2.3V to 12.6V. The inputs can be driven
beyond the supplies without damage or phase reversal of
the output.
The LT1803 is available in the 8-pin SO package with the
standard op amp pinout and in the 5-pin SOT-23 package.
The LT1804 is available in 8-pin DFN and SO packages
with the standard op amp pinouts. The LT1805 features
the standard quad op amp configuration and is available in
a 14-pin plastic SO package.

Note 1: Absolute Maximium Ratings are those values beyond which the
life of the device may be impaired.
Note 2: The inputs are protected by back-to-back diodes and by ESD
diodes to supply rails. If the differential input voltage exceeds 1.4V, or if an
input is driven beyond the supply rails, the input current should be limited
to less than 10mA. This parameter is not tested; however it is guaranteed
by characterization.
Note 3: A heat sink may be required to keep the junction temperature
below the absolute maximum rating when the output is shorted
indefinitely.
Note 4: The LT1803C/LT1803I, LT1804C/LT1804I and LT1805C/LT1805I
are guaranteed functional over the temperature range of –40°C and 85°C.
Note 5: The LT1803C/LT1804C/LT1805C are guaranteed to meet specified
performance from 0°C to 70°C. The LT1803C/LT1804C/LT1805C are
designed, characterized and expected to meet specified performance from
–40°C to 85°C but are not tested or QA sampled at these temperatures.
The LT1803I/LT1804I/LT1805I are guaranteed to meet specified performance from –40°C to 85°C.
Note 6: Minimum supply voltage is guaranteed by power supply rejection
ratio test.
Note 7: Output voltage swings are measured between the output and
power supply rails.
Note 8: This parameter is not 100% tested.
Note 9: Matching parameters are the difference between amplifiers A and
D and between B and C on the LT1805; between the two amplifiers on the
LT1804.
Note 10: Full power bandwidth is based on slew rate:
FPBW = SR/2πVP

Circuit Description
Power Dissipation
The LT1803/LT1804/LT1805 have input and output signal
ranges from the negative power supply to the positive
power supply. Figure 1 depicts a simplified schematic of
one amplifier. The input stage is comprised of two differential amplifiers, a PNP stage Q1/Q2 and an NPN stage Q3/
Q4 that are active over the different ranges of the common
mode input voltage. The PNP differential pair is active
between the negative supply and approximately 1.3V
below the positive supply. As the input voltage moves
toward the positive supply, the transistor Q5 will steer the
tail current I1 to the current mirror Q6/Q7 activating the
NPN differential pair. The PNP pair becomes inactive for
the rest of the input common mode range up to the positive
supply. Also at the input stage, devices Q18 and Q19 act
to cancel the bias current of the PNP input pair. When Q1
and Q2 are active, the current in Q16 is controlled to be the
same as the current in Q1 and Q2; therefore, the base
current of Q16 is nominally equal to the base current of the
input devices. The base current of Q16 is then mirrored by
devices Q17 through Q19 to cancel the base current of the
input devices Q1 and Q2.
There is a need to ensure that the die’s junction temperature does not exceed 150°C. Junction temperature TJ is
calculated from the ambient temperature TA, power dissipation PD and thermal resistance θJA:
A pair of complementary common emitter stages Q14/
Q15 that enable the output to swing from rail-to-rail
constructs the output stage. The capacitors C1 and C2
form the local feedback loops that lower the output
impedance at high frequency. The LT1803/LT1804/LT1805
are fabricated on Linear Technology’s proprietary high
speed complementary bipolar process.
TJ = TA + (PD • θJA)
The power dissipated in the IC is a function of the supply
voltage, amplifier current, output voltage and output current. For a given supply voltage, the worst-case power
dissipation, PDMAX, occurs when the output current and
voltage drop in the amplifier product is maximized. For
example, if the amplifier is sourcing a constant current
then the PDMAX occurs when the output voltage is at about
VS–. On the other hand, for a given load resistance to
ground, the PDMAX will occur when the output voltage is at
half of either supply voltage. PDMAX for a given resistance
to ground is given by:
PDMAX = (VS+ – VS–) ISMAX + (VS/2)2/RL
Example: An LT1804 in an SO-8 package operating on ±5V
supplies and driving a 100Ω load to ground, the PDMAX per
amplifier is given by:
PDMAX = (10 • 3.25mA) + (2.5)2/100 = 0.0425 + 0.0625
= 0.095W
ISMAX is approximated for a typical part from the Supply
Currrent vs Supply Voltage graph.

voltage is typically less than 1000µV in the range the PNP
input stage is active.
The maximum ambient temperature that the part is allowed to operate is:
Input Bias Current
TA = TJ – (PDMAX • 190°C/W)
= 150°C – (0.190W • 190°C/W) = 113.9°C
Similar calculations can be carried out for specific packages and conditions.
Also worth noting, the DD package includes a low θJA
underside metal which is internally connected to VS–. If the
underside metal is properly soldered to a PCB, the θJA of
the part will be close to 50°C/W. This θJA is significantly
less than leaving the underside metal unattached and can
be useful for certain applications.
Input Offset Voltage
The input offset voltage will change greatly based upon
which input stage is active. The PNP input stage is active
from the negative supply voltage to about 1.3V below the
positive supply rail, then the NPN input stage is activated
for the remaining input range up to the positive supply rail
during which the PNP stage remains inactive. The offset
The LT1803/LT1804/LT1805 employ a patent-pending
technique to reduce the input bias current to less than 1µA
for the input common mode voltage range of 0.2V above
the negative supply rail to 1.75V below the positive rail.
The low input offset voltage and low input bias current
provide precision performance in high source impedance
applications.
Output
The LT1803/LT1804/LT1805 can deliver a large output
current, so the short-circuit current limit is set around
50mA to prevent damage to the device. Attention must be
paid to keep the junction temperature of the IC below the
absolute maximum rating of 150°C (refer to the Power
Dissipation section) when the output is continuously short
circuited. The output of the amplifier has reverse-biased
diodes connected to each supply. If the output is forced
beyond either supply, unlimited current will flow through
these diodes. If the current is transient and limited to less
than 100mA and the total supply voltage is less than

APPLICATIO S I FOR ATIO
12.6V, the absolute maximum rating, no damage will
occur to the device.
Overdrive Protection
When the input voltage exceeds the power supplies, two
pairs of crossing diodes D1 through D4 will prevent the
output from reversing polarity. If the input voltage exceeds
either power supply by 700mV, diode D1/D2 or D3/D4 will
turn on to keep the output at the proper polarity. For the
phase reversal protection to perform properly, the input
current must be limited to less than 10mA. If the amplifier
is severely overdriven, an external resistor should be used
to limit the overdrive current.
The LT1803/LT1804/LT1805’s input stages are also protected against a large differential input voltage of 1.4V or
higher by a pair of back-to-back diodes D5 through D8 to
prevent the emitter-base breakdown of the input transistors. The current in these diodes should be limited to less
than 10mA when they are active. The worst-case differential input voltage usually occurs when the input is driven
while the output is shorted to ground in a unity gain
configuration. In addition, the amplifier is protected against
ESD strikes up to 3kV on all pins by a pair of protection
diodes on each pin that is connected to the power supplies
as shown in Figure 1.
Capacitive Load
The LT1803/LT1804/LT1805 are optimized for wide bandwidth, low power and precision applications. They can
drive a capacitive load of about 20pF in a unity-gain
configuration, and more for higher gain. When driving a
larger capacitive load, a resistor of 10Ω to 50Ω should be
connected between the output and the capacitive load to
avoid ringing or oscillation. The feedback should still be
taken from the output so that the resistor will isolate the
capacitive load to ensure stability. Graphs on capacitive
load indicate the transient response of the amplifier when
driving a capacitive load with a specified resistor.
Feedback Components
When feedback resistors are used to set up gain, care must
be taken to ensure that the pole formed by the feedback
resistors and the total capacitance at the inverting input
does not degrade stability. For instance, the LT1803/
LT1804/LT1805 in a noninverting gain of 2 setup with two
5k resistors and a capacitance of 5pF (part plus PC board)
will probably oscillate. The pole formed at 12.7MHz,
reduces phase margin by about 58 degrees when the
crossover frequency of the amplifier is around 20MHz. A
capacitor of 5pF or higher connected across the feedback
resistor will eliminate any ringing or oscillation.
