CAT5259 Datasheet (Catalyst Semiconductor) - Quad Digitally Programmable Potentiometers

CAT5259, Quad Digitally Programmable Potentiometers

The CAT5259 is four digitally programmable poten * tiometers (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 connec
