DESCRIPTION

determined by the logic state of the U/D input. The CS

input is used to select the device.

The CAT5115 is a single digitally programmable

potentiometer (DPP™) designed as a 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 digitally programmable potentiometer can be

used as a three-terminal resistive divider or as a

two-terminalvariableresistor.DPPsbringvariabilityand

programmability to a wide variety of applications

including control, parameter adjustments, and

signal processing.

The CAT5115 contains a 32-tap series resistor array

connected between two terminals R_Hand R_L. An up/

down counter and decoder that are controlled by three

input pins, determines which tap is connected to the

wiper, R_W. The wiper is always set to the mid point, tap

15atpowerup. Thetappositionisnotstoredinmemory.

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

For a pin-compatible device that recalls a stored tap

position on power-up refer to the CAT5114 data sheet.
