ISL22424

Dual Digitally Controlled Potentiometer (XDCP™)

Data Sheet

May 31, 2007

FN6425.0

Low Noise, Low Power, SPI Bus,

256 Taps

Features

• Two potentiometers in one package

• 256 resistor taps

The ISL22424 integrates two digitally controlled

potentiometers (DCP), control logic and non-volatile memory

on a monolithic CMOS integrated circuit.

• SPI serial interface with write/read capability

• Daisy Chain Configuration

• Shutdown mode

The digitally controlled potentiometers are 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. Each potentiometer has an associated

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

user. The contents of the WRi control the position of the

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

DCP’s IVRi to the corresponding WRi.

• Non-volatile EEPROM storage of wiper position

• 13 General Purpose non-volatile registers

• High reliability

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

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

• Wiper resistance: 70Ω typical @ 1mA

• Standby current <4µA max

The ISL22424 also has 13 General Purpose non-volatile

registers that can be used as storage of lookup table for

multiple wiper position or any other valuable information.

• Shutdown current <4µA max

The ISL22424 features a dual supply, that is beneficial for

applications requiring a bipolar range for DCP terminals

• Dual power supply

between V- and V

- V = 2.25V to 5.5V

- V- = -2.25V to -5.5V

Each DCP can be used as three-terminal potentiometer or

as two-terminal variable resistor in a wide variety of

applications including control, parameter adjustments, and

signal processing.

• 10kΩ, 50kΩ or 100kΩ total resistance

• Extended industrial temperature range: -40ºC to +125ºC

• 14 Ld TSSOP or 16 Ld QFN

• Pb-free plus anneal product (RoHS compliant)

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.
