ISL90843
Quad Digital Controlled Potentiometers (XDCP)
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.
Features
Four potentiometers in one package
256 resistor taps–0.4% resolution

NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate
termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
