ISL22424

FN6425

Rev 1.00

September 9, 2015

Dual Digitally Controlled Potentiometer (XDCP™) Low Noise, Low Power, SPI®

Bus, 256 Taps

The ISL22424 integrates two digitally controlled

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

Features

• Two potentiometers in one package

• 256 resistor taps

on a monolithic CMOS integrated circuit.

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.

• SPI serial interface with write/read capability

• Daisy Chain Configuration

• Shutdown mode

• 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

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.

- Register data retention: 50 years @ T 55°C

• Wiper resistance: 70 typical @ 1mA

• Standby current <4µA max

The ISL22424 features a dual supply, that is beneficial for

applications requiring a bipolar range for DCP terminals

• Shutdown current <4µA max

between V- and V

• Dual power supply

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.

- V

= 2.25V to 5.5V

- V- = -2.25V to -5.5V

• 10k 50kor 100k total resistance

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

• 14 Ld TSSOP or 16 Ld QFN

• Pb-free plus anneal product (RoHS compliant)
