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) that can be directly written to and read by the user.
The contents of the WR controls the position of the wiper.
All four potentiometers have one terminal tied to GND.
The DCPs can be used as a resisto...
