CAT5419 Datasheet - ON Semiconductor

CAT5419 Dual Digital Potentiometer

The CAT5419 is two digital POTs integrated with control logic and 16 bytes of NVRAM memory. A separate 6-bit control register (WCR) independently controls the wiper tap position for each digital POT. Associated with each wiper control register are four 6-bit non-volatile memory data registers (DR) u.
