X9119 Datasheet (Renesas) - Digitally Potentiometer

X9119, Digitally Potentiometer

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 thro
