ISL22346WFV20Z, Digital Potentiometer 128-Position Linear, Log I2C 20 Pin

The Renesas Electronics digital potentiometers integrates a single digitally controlled potentiometer (DCP) and non-volatile memory on a monolithic CMOS integrated circuit. It is 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.
