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 devices provide for the option of external
trimming and noise reduction.

Note 1: Temperature coefficient is measured by the box method; i.e., the maximum ∆VOUT is divided by ∆T x VOUT.
Note 2: 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.
Note 3: Noise specifications are 100% tested for the 10Hz to 1kHz bandwidth. Contact factory for 100% noise testing in the 0.1Hz
to 10Hz bandwidth.
Note 4: Temperature hysteresis is specified at TA = +25°C by measuring VOUT before and after changing temperature by +25°C
using the PDIP package.

Voltage Reference Output
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 MAX681 generates approximately ±9V to operate the
MAX6250 reference and MAX432 inverting amplifier. The
+5V is inverted by the MAX432 chopper-stabilized 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.
