® ISL22426 Dual Digitally Controlled Potentiometer (XDCP™) Data Sheet July 17, 2006 FN6180.0 Low Noise, Low Power, SPI® Bus, 128 Taps The ISL22426 integrates two digitally controlled potentiometers (DCP) and non-volatile memory on a monolithic CMOS integrated circuit. The digitally controlled potentiometers are implemented with a combination of resistor elements and CMOS switches. The position of the wipers are controlled by the user through the SPI serial interface. Each potentiometer has an .
