Update: 30 September, 2023
The CAT5259 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 wiper outputs with CMOS switches. A separate 8-bit control register (WCR) independently controls the wiper tap switches for each DPP. Associated with each wiper control register are four 8-bit non-volatile memory data registers (DR) used for storing up to four wiper settings. Writing to the wiper control register or any of the non-volatile data registers automatically loads the wiper settings to the potentiometers, saving switch operation time.
