CAT5128
32‐tap Digital Up/Down
Control Potentiometer (POT)
Description
The CAT5128 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 CAT5128 contains a 32-tap series resistor array connected
between two terminals A and B. An up/down counter and decoder that
are controlled by two input pins, determines which tap is connected to
the wiper, W. Wiper-control of the CAT5128 is accomplished with two
input control pins, UP and DOWN. A high-to-low transition on the UP
input increments the wiper position and a high-to-low transition on the
DOWN input decrements the wiper position. The tap position is not
stored in memory. The wiper is always set to the mid point, tap 15 at
power up.
The digital POT can be used as a three-terminal resistive divider or
as a two-terminal variable resistor. Digital potentiometers bring
variability and programmability to a wide variety of applications
including control, parameter adjustments, and signal processing.
