Description
The CAT5269 is two digital POTs integrated with control logic and 18 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.
