X9259 Datasheet (Xicor) - Quad Digitally-Controlled (XDCP) Potentiometers

X9259, Quad Digitally-Controlled (XDCP) Potentiometers

The X9259 integrates 4 digitally controlled potentiometer (XDCP) on a monolithic CMOS integrated circuit.

The digital controlled potentiometer is implemented using 255 resistive elements in a series array.

Between each element are tap points connected to the wiper terminal through switches.
