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

X9259 Features

* Four separate potentiometers in one package

* 256 resistor taps

* 0.4% resolution

* 2-wire serial interface for write, read, and transfer operations of the potentiometer

* Wiper resistance: 100Ω typical at VCC = 5V

* 4 nonvolatile data registers for ea
