X9401 Datasheet (Renesas) - Quad Digitally Potentiometer

X9401, Quad Digitally Potentiometer

The X9401 integrates 4 digitally controlled potentiometers (XDCP) on a monolithic CMOS integrated microcircuit.

The digitally controlled potentiometer is implemented using 64 resistive elements in a series array.

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