ISL90841

Quad Digitally Controlled Potentiometers (XDCP™)

Data Sheet

August 1, 2005

FN8094.0

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

Features

The ISL90841 integrates four digitally controlled

potentiometers (XDCP) on a monolithic CMOS integrated

circuit.

• Four potentiometers 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.

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.

• Pb-free plus anneal available (RoHS compliant)

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. Contact factory for availability.
