Dual Digitally Programmable Potentiometer (DPP™) With 256 Taps And SPI Interface

The CAT5261 is two Digitally Programmable Potentiometers (DPPs) integrated with control Logic and 8 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 is via a SPI serial bus. On power-up, the contents of the first data Register (DR0) for each of the potentiometers is automatically loaded into its respective wiper control Register
