CAT5128

32-Tap Digital Up/Down

Control Potentiometer

Description

(DPPt) designed as an electronic replacement for mechanical

potentiometers and trim pots. 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.

between two terminals A and B. An up/down counter and decoder that

are controlled by two input pins, determines which tap is connected to

the wiper, W. Wiper−control of the CAT5128 is accomplished with

two input control pins, UP and DOWN. A high−to−low transition on

the UP input increments the wiper position and a high−to−low

transition on the DOWN input decrements the wiper position. The tap

position is not stored in memory. The wiper is always set to the mid

point, tap 15 at power up.

three−terminal resistive divider or as a two−terminal variable resistor.

DPPs bring variability and programmability to a wide variety of

applications including control, parameter adjustments, and signal

processing.
