Overview
CAT5251
Quad Digital
Potentiometer (POT)
with 256 Taps
and SPI Interface
Description
The CAT5251 is four digital POTs integrated with control logic and 16 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 n...
