CAT5409 Datasheet - Catalyst Semiconductor

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.

CAT5409 Features

* Four linear taper digitally programmable potentiometers

* 64 resistor taps per potentiometer

* End to end resistance 2.5kΩ, 10kΩ, 50kΩ or 100kΩ

* I²C interface

* Low wiper resistance, typically 80Ω

* Four non-volatile wiper settings for each potentio
