Overview

CAT5409 Quad Digital Potentiometer (POT) with 64 Taps and I2C Interface Description The CAT5409 is four 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) 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 I2C serial bus.
On power-up, the contents of the first data register (DR0) for each of the four potentiometers is automatically loaded into its respective wiper control register (WCR...
