DESCRIPTION

The CAT5111 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.

The CAT5111 contains a 100-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

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

setting.

accomplished with three input control pins, CS

and INC

direction which is determined by the logic state of the

U/D ¯ input. The CS

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 CAT5113. The

buffered wiper of the CAT5111 is not compatible with

that application.
