CAT5419
Dual Digital
Potentiometer (POT)
with 64 Taps
and 2‐wire Interface
Description
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) 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 2-wire serial bus (I2C-like). On power-up, the contents of the first data register (DR0) for each of the two potentiometers is automatically loaded into its respective wiper control registers (WCR).
