CAT5115

32-Tap Digitally Programmable Potentiometer (DPP™)

FEATURES

32-position linear taper potentiometer

Low power CMOS technology

Single supply operation: 2.5V – 6V

Increment up/down serial interface

Resistance values: 10kΩ, 50kΩ and 100kΩ

Available in PDIP, SOIC, TSSOP, MSOP and

space saving 2 x 2.5mm TDFN packages

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

and R

. An

up/down counter and decoder that are controlled by

three input pins, determines which tap is connected to

the wiper, R

. 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 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 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.

APPLICATIONS

Automated product calibration

Remote control adjustments

Offset, gain and zero control

Tamper-proof calibrations

Contrast, brightness and volume controls

Motor controls and feedback systems

Programmable analog functions
