ISL22319

Single Digitally Controlled Potentiometer (XDCP™)

Data Sheet

July 3, 2006

FN6310.0

Low Noise, Low Power, I C^®Bus,

128 Taps, Wiper Only

Features

• 128 resistor taps

The ISL22319 integrates a single digitally controlled

potentiometer (DCP) and non-volatile memory on a

monolithic CMOS integrated circuit.

• I C serial interface

- Two address pins, up to four devices/bus

• Non-volatile storage of wiper position

• Wiper resistance: 70Ω typical @ 3.3V

• Shutdown mode

The digitally controlled potentiometer is 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. The potentiometer has an associated

• Shutdown current 5µA max

• Power supply: 2.7V to 5.5V

• 50kΩ or 10kΩ total resistance

• High reliability

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 content of the

DCP’s IVR to the WR.

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

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

of applications including control, parameter adjustments, AC

measurement and signal processing.

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

• 8 Ld MSOP

• 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.
