DESCRIPTION
The CAT5112 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 CAT5112 contains a 32-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
AMP that operates rail to rail. The wiper setting, stored
in non-volatile NVRAM memory, is not lost when the
device is powered down and is automatically recalled

setting.
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. DPPs bring variability and
programmability to a wide variety of applications
including control, parameter adjustments, and
signal processing.
