CAT5128
32-Tap Digital Up/Down
Control Potentiometer
Description
(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.
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.
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.
