X9111
Single Supply/Low Power/1024-Tap/SPI Bus/Single Digitally-Controlled (XDCP™) Potentiometer
FN8159 Rev 5.00 October 13, 2016
The X9111 integrates a single, digitally controlled potentiometer (XDCP) on a monolithic CMOS integrated circuit.
The digital controlled potentiometer is implemented using 1023 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 SPI bus interface. The potentiometer has associated with it a volatile Wiper Counter Register (WCR) and four nonvolatile Data Registers that can be directly written to and read by the user.
