CAT5110/5118/5119

Adjustable Gain

APPLICATIONS INFORMATION

Figure 5 shows how to use the variable resistor to

digitally adjust the gain of a noninverting op amp

configuration. Connect the CAT5119 in series with a

resistor to ground to form the adjustable gain control of

a noninverting amplifier. The Minipots have a low 5ppm/

˚C ratiometric tempco that allows for a very stable

adjustable gain configuration over temperature.

The Minipots are intended for circuits requiring digitally

controlled adjustable resistance, such as LCD contrast

control, where voltage biasing adjusts the display con-

trast.

Alternative Positive LCD Bias Control

Use an op amp to provide buffering and gain on the

output of the CAT5110. Connect the mechanical

potentiometer 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 CAT5119.
