CAT5133 Datasheet (Catalyst Semiconductor) - Digitally Programmable Potentiometer

CAT5133, Digitally Programmable Potentiometer

The CAT5133 is a high voltage Digital Programmable Potentiometer (DPP) integrated with E2PROM memory and control logic to operate in a similar manor to a mechanical potentiometer.

The DPP consists of a series of resistive elements connected between two externally accessible end points.
