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
