CAT5114
32-Tap Digitally Program-
mable Potentiometer (DPPt)
Description
The CAT5114 is a single digitally programmable potentiometer
(DPPt) designed as an 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 CAT5114 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 wiper setting, stored in nonvolatile
W
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 affecting the stored setting.
Wiper−control of the CAT5114 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.
DPPs bring variability and programmability to a wide variety of
applications including control, parameter adjustments, and signal
processing.
