CAT5251 Datasheet (Catalyst Semiconductor) - Quad Digitally Programmable Potentiometer

CAT5251, Quad Digitally Programmable Potentiometer

The CAT5251 is four Digitally Programmable Potentiometers (DPPs™) integrated with control logic and 16 bytes of NVRAM memory.

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

The tap points between each resistive element are connected to the
