Characteristics subject to change without notice
The CAT5116 is a log-taper 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, 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
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 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.
The digitally programmable potentiometer can be
used as a three-terminal resistive divider or as a
two-terminal variable resistor.
