DESCRIPTION

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 CAT5115 contains a 32-tap series resistor array

connected between two terminals R

up/down counter and decoder that are controlled by

three input pins, determines which tap is connected to

the wiper, R

point, 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

and INC

direction which is determined by the logic state of the

U/D ¯ input. The CS

The digitally programmable potentiometer can be used

as a three-terminal resistive divider or as a two-terminal

variable resistor. DPPs bring variability and program-

mability 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.
