DATASHEET X9110 Dual Supply/Low Power/1024-Tap/SPI Bus, Single Digitally-Controlled (XDCP™) Potentiometer FN8158 Rev 5.00 October 28, 2016 The X9110 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 th
