Applications Information
controlled adjustable resistance, such as LCD contrast
control, where voltage biasing adjusts the display contrast.
Alternative Positive LCD Bias Control
the output of the CAT5110/CAT5125. This can be done by
connecting the wiper output to the positive input of a
noninverting op amp as shown in Figure 9. Figure 10 shows
a similar circuit for the CAT5119/CAT5124.
The MiniPots are intended for circuits requiring digitally
An op amp can be used to provide buffering and gain on

Adjustable Gain
resistor or a potentiometer to digitally adjust the gain of a
noninverting op amp configuration, by connecting the
Minipot in series with a resistor to ground. The MiniPots
have a low 5 ppm/°C ratiometric tempco that allows for a
very stable adjustable gain configuration over temperature.
