Quad Digitally Controlled Potentiometers (XDCP)
Low Noise, Low Power I

C
Bus, 256 Taps
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
I
2
C 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 resistor divider or as two-terminal
variable resistors in a wide variety of applications including
control, parameter adjustments, and signal processing.

NOTES:
1. 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.
