Intersil X9409
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. The position of the wiper on the array is controlled by the user through the 2-wire bus interface.| Part No. | X9409 |
