Low Noise, Low Power, I2C® Bus,
256 Taps
The ISL90843 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.
The DCPs can be used as a voltage divider in a wide variety
of applications including control, AC measurement, and
signal processing.
