Low Noise/Low Power/2-Wire Bus Quad Digitally Controlled Potentiometers
Rev.6.00
(XDCP)
Sep 3, 2015
The X9409 integrates 4 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 switches. The position of the wiper on the array is controlled by the user through the 2-wire bus interface.
