APPLICATIONS INFORMATION

The MiniPots are intended for circuits requiring

digitally controlled adjustable resistance, such as LCD

contrast control, where voltage biasing adjusts the

display contrast.

Adjustable Gain

Figure 5 shows how to use either a variable 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 5ppm/ºC ratiometric tempco that

allows for a very stable adjustable gain configuration

over temperature.

Alternative Positive LCD Bias Control

An op amp can be used to provide buffering and gain

on 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 3.

Figure 4 shows a similar circuit for the CAT5119/

CAT5124.
