DATASHEET X9259 Single Supply/Low Power/256-Tap/2-Wire Bus Quad Digitally-Controlled (XDCP™) Potentiometers FN8169 Rev 6.00 December 12, 2014 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 associated with it 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.
