DATASHEET X9119 1024 Tap, Low Power, 2-Wire Interface, Digitally Controlled (XDCP™) Potentiometer FN8162 Rev 5.00 July 5, 2016 The X9119 integrates a single digitally controlled potentiometer (XDCP™) on a monolithic CMOS integrated circuit. The digital controlled potentiometer is implemented using 1023 resistive elements in a series array. Between each element are tap points connected to the wiper terminal through switches. The position of the wiper on the array is controlled by the user through the 2-wire bus interface. The 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.
