DESCRIPTION
The CAT5116 is a log-taper single digitally program-
mable potentiometer (DPP™) designed as a electro-
nic replacement for mechanical potentiometers.
Ideal for automated adjustments on high volume
production lines, DPP ICs are well suited for applica-
tions where equipment requiring periodic adjustment
is either difficult to access or located in a hazardous or
remote environment.
The CAT5116 contains a 100-tap series resistor array
connected between two terminals R
up/down counter and decoder that are controlled by
three input pins, determines which tap is connected to
the wiper, R
The wiper setting, stored in nonvolatile 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 effecting the stored setting.
Wiper-control of the CAT5116 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.
