Quad Digitally Controlled Potentiometers (XDCP™)

Data Sheet

July 28, 2006

FN6177.0

Low Noise, Low Power I C^®Bus, 128 Taps

Features

The ISL22346 integrates four digitally controlled

potentiometers (DCP) and non-volatile memory on a

monolithic CMOS integrated circuit.

• Four potentiometers in one package

• 128 resistor taps

• 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

• Non-volatile storage of wiper position

• Wiper resistance: 70Ω typical @ 3.3V

• Shutdown mode

I C bus interface. Each potentiometer has an associated

volatile Wiper Register (WR) and a non-volatile Initial Value

user. The contents of the WR controls the position of the

wiper. At power-up the device recalls the contents of the two

DCP’s IVR to the corresponding WRs.

• Shutdown current 5µA max

• Power supply: 2.7V to 5.5V

• 50kΩ or 10kΩ total resistance

The DCPs can be used as a three-terminal potentiometers

or as a two-terminal variable resistors in a wide variety of

applications including control, parameter adjustments, and

signal processing.

• High reliability

- Endurance: 1,000,000 data changes per bit per register

- Register data retention: 50 years @ T <55°C

• 20 Ld TSSOP

Pinout

• Pb-free plus anneal product (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. Add “-TK” suffix for 1,000 Tape and Reel option

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