Quad Digitally Controlled Variable Resistors

Data Sheet

January 16, 2006

FN8096.1

Low Noise, Low Power I C^®Bus, 256 Taps

Features

The ISL90842 integrates four digitally controlled

potentiometers (DCP) configured as variable resistors on a

monolithic CMOS integrated circuit.

• Four variable resistors in one package

• 256 resistor taps - 0.4% resolution

• I C serial interface

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

• Wiper resistance: 70Ω typical @ 3.3V

• Standby current <5µA max

• Power supply: 2.7V to 5.5V

• 50kΩ, 10kΩ total resistance

• 14 Lead TSSOP

I 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.

The DCPs can be used as two-terminal variable resistors in

a wide variety of applications including control, parameter

adjustments, and signal processing.

• Pb-free plus anneal available (RoHS compliant)

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.

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
