CAT5114
32‐tap Digital
Potentiometer (POT)
Description
The CAT5114 is a single digital POT 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 RH and RL. An up/down counter and decoder
that are controlled by three input pins, determines which tap is
connected to the wiper, RW. 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 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 digital POT can be used as a three-terminal resistive divider or
as a two-terminal variable resistor. Digital POTs bring variability and
programmability to a wide variety of applications including control,
parameter adjustments, and signal processing.
