DATASHEET
ISL90842
Quad Digitally Controlled Variable Resistors Low Noise, Low Power I2C Bus, 256 Taps
FN8096
Rev 1.00
January 16, 2006
The ISL90842 integrates four digitally controlled
potentiometers (DCP) configured as variable resistors 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 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.
2. Add “-TK” suffix for Tape and Reel.
