Low Noise, Low Power, I C Bus,

Features

• Four potentiometers in one package

256 Taps

The ISL90843 integrates four digitally controlled

potentiometers (XDCP) on a monolithic CMOS integrated

circuit.

• 256 resistor taps–0.4% resolution

• I C serial interface

- Two address pins allow up to four devices/bus

• Wiper resistance: 70Ω typical @ 3.3V

• Standby current <5µA max

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 C bus interface. Each potentiometer has an associated

• Power supply: 2.7V to 5.5V

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.

• 10kΩ or 50kΩ total resistance

• 10 Ld MSOP package

The DCPs can be used as a voltage divider in a wide variety

of applications including control, AC measurement, and

signal processing.

• Pb-free plus anneal product (RoHS compliant)

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.

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