Quad Digitally Controlled Potentiometers (XDCP™)

Data Sheet

September 15, 2006

FN6331.2

2 ®

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

Wiper Only

Features

• Four potentiometers in one package

• 128 resistor taps

The ISL22349 integrates four digitally controlled

potentiometers (DCP) and non-volatile memory on a

monolithic CMOS integrated circuit.

• I C serial interface

- Three address pins, up to eight devices/bus

• Non-volatile storage of wiper position

• Wiper resistance: 70Ω typical

• Shutdown mode

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

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 6.5µA max

• Power supply: 2.7V to 5.5V

• 50kΩ or 10kΩ total resistance

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

of applications including control, parameter adjustments, AC

measurement and signal processing.

• High reliability

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

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

• 14 Ld TSSOP

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.
