Adjustable Voltage Reference
Figure 12 shows the MAX5417/MAX5418/MAX5419 used
as the feedback resistors in multiple adjustable voltage-
reference applications. Independently adjust the output
voltage of the MAX6160 from 1.23V to V
IN
- 0.2V by
changing the wiper positions of the MAX5417/
MAX5418/MAX5419.
Offset Voltage and Gain Adjustment
Connect the high and low terminals of one potentiometer
of a MAX5417 between the NULL inputs of a MAX410
and the wiper to the op amp’s positive supply to nullify
the offset voltage over the operating temperature range.
Install the other potentiometer in the feedback path to
adjust the gain of the MAX410 (see Figure 13).
