X9118, Dual Supply/Low Power/1024-Tap/2-Wire Bus Single Digitally-Controlled Potentiometer

DATASHEET X9118 Dual Supply/Low Power/1024-Tap/2-Wire Bus Single Digitally-Controlled (XDCP™) Potentiometer FN8161 Rev 5.00 April 9, 2014 The X9118 is 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 th
