ISL90841, Quad Digitally Controlled Potentiometers Low Noise Low Power I2C

DATASHEET ISL90841 Quad Digitally Controlled Potentiometers (XDCP™) Low Noise, Low Power I2C FN8094 Rev 1.00 February 8, 2006 The ISL90841 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) t
