CAT5112/D
CAT5112
32‐tap Digital
Potentiometer (POT)
with Buffered Wiper
Description
The CAT5112 is a single digital POT designed as an electronic
replacement for mechanical potentiometers. 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 RH and RL. An up/down counter and decoder
that are controlled by three input pins, determines which tap is
connected to the wiper, RWB. The CAT5112 wiper is buffered by an op
amp that operates rail to rail. The wiper setting, stored in non-volatile
memory, is not lost when the device is powered down and is
automatically recalled when power is returned. The wiper can be
adjusted to test new system values without effecting the stored setting.
Wiper-control of the CAT5112 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 digital POT can be used as a buffered voltage divider. For
applications where the potentiometer is used as a 2-terminal variable
resistor, please refer to the CAT5114. The buffered wiper of the
CAT5112 is not compatible with that application.
