CAT5261
CAT5261 is Dual Digital Potentiometer manufactured by onsemi.
Dual Digital Potentiometer (POT) with 256 Taps and SPI Interface
Description The CAT5261 is two digital POTs integrated with control logic and
8 bytes of NVRAM memory. Each digital POT 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 digital POT. 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...
