CAT5115/D

CAT5115

32‐tap Digital

Potentiometer (POT)

Description

The CAT5115 is a single digital POT 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.

The CAT5115 contains a 32-tap series resistor array connected

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

tap 15 at power up. The tap position is not stored in memory.

Wiper-control of the CAT5115 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.

The digital POT can be used as a three-terminal resistive divider or

as a two-terminal variable resistor. Digital POTs bring variability and

programmability to a wide variety of applications including control,

parameter adjustments, and signal processing.

For a pin-compatible device that recalls a stored tap position on

power-up refer to the CAT5114 data sheet.
