Single Digitally Controlled Potentiometer (XDCP™) Low Noise/Low Power/I2C Bus/256 Taps
FN8234 Rev 3.00 September 10, 2015
The ISL90810 integrates a digitally controlled potentiometer (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. When powered on the ISL90810’s wiper will always commence at mid-scale (128 tap position).
The DCP can be used as three-terminal potentiometer or as two-terminal variable resistor in a wide variety of applications including control, parameter adjustments, and signal processing.
