ISL90840

Quad Digitally Controlled Potentiometers (XDCP™)

Data Sheet

November 14, 2006

FN8086.2

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

Features

The ISL90840 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

- Three address pins, up to eight devices/bus

- Write/Read capability

I C bus interface. Each potentiometer has an associated

• Power-on preset to mid-scale (128 tap position)

• Wiper resistance: 70 typical @ 3.3V

• Standby current <5µA max

volatile 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. When powered on the ISL90810’s

wiper will always commence at mid-scale (128 tap position).

• Power supply: 2.7V to 5.5V

The DCPs can be used as three-terminal potentiometers or

as two-terminal variable resistors in a wide variety of

applications including control, parameter adjustments, and

signal processing.

• 50k, 10k total resistance

• 20 Ld TSSOP package

• Pb-free plus anneal available (RoHS compliant)

NOTES:

20 Ld TSSOP (Pb-free)

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 “T2” suffix for tape and reel.

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