X9401 Description
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.
