DATASHEET  
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  
Register (IVRi) that can be directly written to and read by the  
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: 70typical @ 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  
.
CC  
• 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

• 10k 50kor 100ktotal resistance  
• Extended industrial temperature range: -40ºC to +125ºC  
• 14 Ld TSSOP or 16 Ld QFN  
• Pb-free plus anneal product (RoHS compliant)
