The MAX873/MAX875/MAX876 precision voltage refer-
ences provide accurate preset +2.5V, +5.0V, and +10V
reference voltages from up to +40V input voltages. These
devices feature a proprietary temperature-coefficient
curvature-correction circuit and laser-trimmed thin-film
resistors that result in a very low 3ppm/°C temperature
coefficient and excellent 0.05% initial accuracy. The
MAX873/MAX875/MAX876 draw 340µA of supply current
and source 30mA or sink 2mA of load current.
Trim the factory-preset output voltage on the
MAX873/MAX875/MAX876 by placing a resistive divider
network between OUT, TRIM, and GND.

Use the following formula to calculate the change in
output voltage from its preset value:

k = ±6% (typ)
For example, use a 50kΩ potentiometer (such as the
MAX5436) between OUT, TRIM, and GND with the
potentiometer wiper connected to TRIM (see Figure 2).
As the TRIM voltage changes from V
output voltage changes accordingly. Set R2 to 1MΩ or
less. Currents through resistors R1 and R2 add to the
quiescent supply current.
