DESCRIPTION

The CAT5114 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 CAT5114 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 setting, stored in nonvolatile

memory, is not lost when the device is powered

down and is automatically reinstated when power

is returned. The wiper can be adjusted to test

new system values without effecting the stored

setting. Wiper-control of the CAT5114 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

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 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.
