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
