MAX5160/MAX5161
Alternative Positive
LCD Bias Control
Alternatively, use an op amp to provide buffering and
gain to the output of the MAX5160/MAX5161. Connect
the MAX5160 to the positive input of a noninverting op
amp (Figure 3) to select a portion of the input signal by
digitally controlling the wiper terminal. Figure 4 shows a
similar circuit for the MAX5161.
Adjustable Gain
Figure 5 shows how to use the MAX5161 to digitally
adjust the gain of a noninverting op amp configuration.
Connect the MAX5161 in series with a resistor to ground
to form the adjustable gain control of a noninverting
amplifier. The MAX5160/MAX5161 have a low 5ppm/°C
ratiometric tempco that allows for a very stable adjust-
able gain configuration over temperature.
