The MiniPots are intended for circuits requiring digitally
controlled adjustable resistance, such as LCD contrast
control, where voltage biasing adjusts the display
contrast.

An op amp can be used to provide buffering and gain on
the output of the CAT50/CAT525. 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 CAT59/CAT524.

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.
