CAT5419 Dual Digitally Programmable Potentiometer

The CAT5419 is two 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 6bit non-volatile memor.
