ISL22346WM
Quad Digitally Controlled Potentiometers (XDCP™)
Data Sheet
November 11, 2011
FN6624.1
Low Noise, Low Power I2C® Bus, 128 Taps
The ISL22346WMVEP integrates four 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 I2C bus interface. Each potentiometer has an associated volatile Wiper Register (WR) and a non-volatile Initial Value Register (IVR) that can be directly written to and read by the user. The contents of the WR controls the position of the wiper.
