DATASHEET X9118 Dual Supply/Low Power/1024-Tap/2-Wire Bus Single Digitally-Controlled (XDCP™) Potentiometer FN8161 Rev 5.00 April 9, 2014 The X9118 is 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 a four non-volatile Data Registers that can be directly written to and read by the user.
