CAT5112

32-Tap Digitally Programmable Potentiometer (DPP™)

with Buffered Wiper

FEATURES

DESCRIPTION

The CAT5112 is a single digitally programmable

potentiometer (DPP™) designed as a electronic

replacement for mechanical potentiometers. 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.

32-position linear taper potentiometer

Non-volatile EEPROM wiper storage;

buffered wiper

Low power CMOS technology

Single supply operation: 2.5V-6.0V

Increment up/down serial interface

Resistance values: 10kΩ, 50kΩ and 100kΩ

The CAT5112 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_WB. The CAT5112 wiper is buffered by an

op amp that operates rail to rail. The wiper setting,

stored in non-volatile memory, is not lost when the

device is powered down and is automatically recalled

when power is returned. The wiper can be adjusted to

test new system values without effecting the stored

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

and also store the wiper position prior to power down.

The digitally programmable potentiometer can be

used as a buffered voltage divider. For applications

where the potentiometer is used as a 2-terminal

variable resistor, please refer to the CAT5114. The

buffered wiper of the CAT5112 is not compatible with

that application.
