Description:

Quad digitally programmable potentiometers.

CAT5409, Quad Digitally Programmable Potentiometers

The CAT5409 is four Digitally Programmable Potentiometers (DPP™) 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 DPP.

Associated with each wiper control register are four 6-bit non-volatile mem
