Manufacturer: Intersil (now Renesas)

Overview

POSSIOBBLSEOSLUEBXTS9E5TP8IT4RU0OTDEUPDCRaTOtaDSUhCeTet ISL90840 Quad Digitally Controlled Potentiometers (XDCP™) November 14, 2006 FN8086.2 Low Noise, Low Power I2C® Bus, 256 Taps The ISL90840 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.
