DESCRIPTION
The CAT5114 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 CAT5114 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
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
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.
