X9400 Description
The X9400 integrates four digitally controlled potentiometers (XDCPs) on a monolithic CMOS integrated circuit. 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 switches.
