CAT5112

32‐tap Digital

Potentiometer (POT)

with Buffered Wiper

Description

The CAT5112 is a single digital POT designed as an electronic

replacement for mechanical potentiometers. Ideal for automated

adjustments on high volume production lines, they are also well suited

for applications where equipment requiring periodic adjustment is

either difficult to access or located in a hazardous or remote

environment.

Z SUFFIX

The CAT5112 contains a 32-tap series resistor array connected

CASE 751BD

CASE 846AD

between two terminals R and R . An up/down counter and decoder

that are controlled by three input pins, determines which tap is

connected to the wiper, R . The CAT5112 wiper is buffered by an op

amp that operates rail to rail. The wiper setting, stored in non-volatile

memory, is not lost when the device is powered down and is

automatically recalled when power is returned. The wiper can be

adjusted to test new system values without effecting the stored setting.

Wiper-control of the CAT5112 is accomplished with three input

control pins, CS, U/D, and INC. The INC input increments the wiper

in the direction which is determined by the logic state of the U/D input.

The CS input is used to select the device and also store the wiper

position prior to power down.

PIN CONFIGURATIONS

The digital POT can be used as a buffered voltage divider. For

applications where the potentiometer is used as a 2-terminal variable

resistor, please refer to the CAT5114. The buffered wiper of the

CAT5112 is not compatible with that application.
