22346WMVEP Datasheet | Intersil

ISL22346WM Quad Digitally Controlled Potentiometers (XDCP™) Low Noise, Low Power I2C Bus, 128 Taps FN6624 Rev 1.00 November 11, 2011 The ISL22346WMVEP integrates four digitally controlled potentiometers (DCP) and non-volatile memory on a monolithic CMOS integrated circuit. The digitally controlled potentiometers are implemented with a bination 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...
