DATASHEET X9252 Low Power + Quad 256-tap + 2-Wire Bus + Up/Down Interface Quad Digitally-Controlled (XDCP™) Potentiometer FN8167 Rev 3.1 Jul 1, 2021 The X9252 integrates 4 digitally controlled potentiometers (XDCP) on a monolithic CMOS integrated circuit. The digitally controlled potentiometers are implemented using 255 resistive elements in a series array. Between each pair of elements are tap points connected to wiper terminals through switches. The position of each wiper on the array is controlled by the user through the Up/Down (U/D) or 2-wire bus interface. The wiper of each potentiometer has an associated volatile Wiper Counter Register (WCR) and four nonvolatile Data Registers (DRs) that can be directly written to and read by the user.
