Overview
DATASHEET X9110 Dual Supply/Low Power/1024-Tap/SPI Bus, Single Digitally-Controlled (XDCP™) Potentiometer FN8158 Rev 5.
00 October 28, 2016 The X9110 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.
The contents of the WCR controls the position of the wiper on the resistor array though the switches.
Power-up recalls the contents of the default data register (DR0) to the WCR.
The XDCP can be used as a three-terminal potentiometer or as a two terminal variable resistor in a wide variet...
