® ISL90843 Quad Digital Controlled Potentiometers (XDCP™) Data Sheet March 29, 2006 FN8095.2 Low Noise, Low Power, I2C® Bus, 256 Taps The ISL90843 integrates four digitally controlled potentiometers (XDCP) 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 Wiper Register (WR) that can be directly written to and read by the user. The contents of the WR controls the position of the wiper. The DCPs can be used as a voltage divider in a wide variety of applications including control, AC measurement, and signal processing.
