ISL22326 Dual Digitally Controlled Potentiometers

Datasheet ISL22326 Dual Digitally Controlled Potentiometers (XDCP™) Low Noise, Low Power, I2C Bus, 128 Taps The ISL22326 integrates two digitally controlled potentiometers (XDCP) 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 I2C bus interface. Each potentiometer has an associated volatile Wiper Reg.
