X9420 Low Noise/Low Power/SPI Bus Single Digitally Controlled XDCP Potentiometer

The X9420 integrates a single digitally controlled potentiometers (XDCP) on a monolithic CMOS integrated microcircuit. The digitally controlled potentiometer is implemented using 63 resistive elements in a series array. Between each element are tap points connected to the wiper terminal through swit.
