CAT5112
32-Tap Digitally Program-
mable Potentiometer (DPPt)
with Buffered Wiper
Description
The CAT5112 is a single digitally programmable potentiometer
(DPPt) 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 R
and R
. An up/down counter and decoder
H
L
that are controlled by three input pins, determines which tap is
connected to the wiper, R
. The CAT5112 wiper is buffered by an op
WB
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 digitally programmable potentiometer 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.
