X9421 - Single Digitally Potentiometer
The X9421 integrates a single digitally controlled potentiometer (XDCP) on a monolithic CMOS integrated circuit.
The digital controlled potentiometer is implemented using 63 resistive elements in a series array.
Between each element are tap points connected to the wiper terminal through switches.
