MAX6225/MAX6241/MAX6250
General Description
The MAX6225/MAX6241/MAX6250 are low-noise, precision voltage references with extremely low 1ppm/°C
temperature coefficients and excellent ±0.02% initial
accuracy. These devices feature buried-zener technology for lowest noise performance. Load-regulation specifications are guaranteed for source and sink currents
up to 15mA. Excellent line and load regulation and low
output impedance at high frequency make them ideal
for high-resolution data-conversion systems up to
16 bits.
The MAX6225 is set for 2.500V output, the MAX6241 is
set for 4.096V output, and the MAX6250 is set for
5.000V output. All three provide for the option of external trimming and noise reduction.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Temperature coefficient is measured by the box method; i.e., the maximum ∆VOUT is divided by ∆T x VOUT.
Line regulation (∆VOUT / (VOUT x ∆VIN)) and load regulation (∆VOUT / (VOUT x ∆IOUT)) are measured with pulses and do
not include output voltage changes due to die-temperature changes.
Noise specifications are guaranteed by design.
Temperature hysteresis is specified at TA = +25°C by measuring VOUT before and after changing temperature by +25°C
using the PDIP package.

Noise Reduction
To augment wideband noise reduction, add a 1µF
capacitor to the NR pin (Figure 2). Larger values do not
improve noise appreciably (see Typical Operating
Characteristics).
Noise in the power-supply input can affect output
noise, but can be reduced by adding an optional
bypass capacitor to the IN pin and GND.
Bypassing
The MAX6225/MAX6241/MAX6250 are stable with
capacitive load values from 0µF to 100µF, for all values
of load current. Adding an output bypass capacitor can
help reduce noise and output glitching caused by load
transients.

Detailed Description
Temperature Stability
The MAX6225/MAX6241/MAX6250 are highly stable,
low-noise voltage references that use a low-power temperature-compensation scheme to achieve laboratorystandard temperature stability. This produces a nearly
flat temperature curve, yet does not require the power
associated with heated references.
The output voltage can be trimmed a minimum of 0.6%
by connecting a 10kΩ potentiometer between OUT and
GND, and connecting its tap to the TRIM pin, as shown
in Figure 1. The external trimming does not affect temperature stability.
Figure 3 shows how both a +5V and -5V precision reference can be obtained from a single unregulated +5V
supply. A MAX865 generates approximately ±9V to
operate the MAX6250 reference and MAX432 inverting
amplifier. The +5V is inverted by the MAX432 chopperstabilized amplifier. Resistor R1 is optional, and may be
used to trim the ±5V references. R2 and R4 should be
matched, both in absolute resistance and temperature
coefficient. R3 is optional, and is adjusted to set the -5V
reference.
