Quad Digitally Controlled Potentiometers (XDCP™) Low Noise, Low Power, I2C™ Bus, 128 Taps, Wiper Only
FN6331 Rev 3.00 May 28, 2009
The ISL22349 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.
