ISL22419

Single Digitally Controlled Potentiometer (XDCP™)

Data Sheet

June 28, 2006

FN6311.0

Low Noise, Low Power, SPI Bus, 128 Taps,

Wiper Only

Features

• 128 resistor taps

• SPI serial interface

The ISL22419 integrates a single digitally controlled

potentiometer (DCP) and non-volatile memory on a

monolithic CMOS integrated circuit.

• 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 wiper is controlled by the user through the SPI

serial interface. The 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 content of the

DCP’s IVR to the WR.

• Shutdown current 5µA max

• Power supply: 2.7V to 5.5V

• 50kΩ or 10kΩ total resistance

• High reliability

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

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

• 8 Lead MSOP

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

of applications including control, parameter adjustments, AC

measurement and signal processing.

• 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.
