Description
   The CAT5411 is two digital potentiometers (POTs) integrated with control logic and 16 bytes of NVRAM memory. Each digital POT consists of a series of 63 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.
