Quad Digitally-Controlled (XDCP™) Potentiometer Evaluation Board

The X9259EVAL board is used to evaluate the X9259 single supply/low power/256-tap/2-wire bus, quad digitally-controlled (XDCP™) potentiometer. The X9259 integrates four digitally controlled potentiometers (XDCP) on a monolithic CMOS integrated circuit. The digitally controlled potentiometers are implemented with a combination of resistor elements and CMOS switches. The position of the wipers are controlled by the user through the 2-wire bus interface. Each potentiometer has a volatile wiper counter register (WCR) and four nonvolatile data registers that can be directly written to and read by the user. The content of the WCR controls the position of the wiper. At power-up, the device recalls the content of the default data registers of each DCP (DR00, DR10, DR20, and DR30) to the corresponding WCR.
