32-Tap Digitally Programmable Potentiometer (DPP™)

FEATURES

s 32-position, linear-taper potentiometer

s Low power CMOS technology

s Single supply operation: 2.5V-5.5V

s Increment up/down serial interface

s Resistance values: 10k

s Available in PDIP, SOIC, TSSOP and MSOP packages

determined by the logic state of the U/

D input. The CS

input is used to select the device.

The digitally programmable potentiometer can be

used as a 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.

For a pin-compatible device that recalls a stored tap

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

FUNCTIONAL DIAGRAM

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 RH and RL. An up/

down counter and decoder that are controlled by three

input pins, determines which tap is connected to the

wiper, RW. The wiper is always set to the mid 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, U/D, and INC. The INC

input increments the wiper in the direction which is
