Single Digitally Controlled Potentiometer (XDCP™) Low Noise, Low Power, I2C Bus, 128 Taps, Wiper Only
DATASHEET
FN6310 Rev 1.00 September 9, 2009
The ISL22319 integrates a single digitally controlled potentiometer (DCP) and non-volatile memory on a monolithic CMOS integrated circuit.
The digitally controlled potentiometer 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. The 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.
