Use the following equations to calculate the gain (A)
and the -3dB cutoff frequency (fC):
Adjustable Voltage Reference
Figure 7 shows the MAX5487/MAX5488/MAX5489 used
as the feedback resistors in multiple adjustable volt-
age-reference applications. Independently adjust the
output voltages of the MAX6160s from 1.23V to VIN -
0.2V by changing the wiper positions of the MAX5487/
MAX5488/MAX5489.
Offset Voltage and Gain Adjustment
Connect the high and low terminals of one potentiome-
ter of a MAX5487/MAX5488/MAX5489 to the NULL
inputs of a MAX410, and connect 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 8).
