CAT5261 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.
