DESCRIPTION

The CAT5116 is a log-taper single digitally

programmable potentiometer (DPP™) designed as a

electronic replacement for mechanical potentiometers

and trim pots.

automatically reinstated when power is returned. The

wipercanbeadjustedtotestnewsystemvalueswithout

effecting the stored setting.

Wiper-control of the CAT5116 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.

Ideal for automated adjustments on high volume

production lines, DPP ICs are well suited for

applications where equipment requiring periodic

adjustment is either difficult to access or located in a

hazardous or remote environment.

The CAT5116 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 digitally programmable potentiometer can be

used as a three-terminal resistive divider or as a

two-terminal variable resistor.

The wiper setting, stored in nonvolatile memory, is not

lost when the device is powered down and is
