DESCRIPTION

new system values without effecting the stored

setting. Wiper-control of the CAT5113 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 and also store the wiper position prior to

power down.

The CAT5113 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 digitally programmable potentiometer can be

used as a three-terminal resistive divider or as a

two-terminalvariableresistor.DPPsbringvariabilityand

programmability to a wide variety of applications

including control, parameter adjustments, and

signal processing.

The CAT5113 contains a 100-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_W. 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
