ISL22449  
®
Quad Digitally Controlled Potentiometer (XDCP™)  
Data Sheet  
®
September 15, 2006  
FN6333.2  
Low Noise, Low Power, SPI Bus, 128 Taps,  
Wiper Only  
Features  
• Four potentiometers in one package  
• 128 resistor taps  
The ISL22449 integrates four digitally controlled  
potentiometers (DCP) and non-volatile memory on a  
monolithic CMOS integrated circuit.  
• SPI serial interface  
The digitally controlled potentiometers are implemented with  
a combination of resistor elements and CMOS switches. The  
position of the wipers are controlled by the user through the  
SPI serial interface. Each potentiometer has an associated  
volatile Wiper Register (WR) and a non-volatile Initial Value  
Register (IVR) that can be directly written to and read by the  
user. The contents of the WR controls the position of the  
wiper. At power-up the device recalls the contents of the  
DCP’s IVR to the corresponding WR.  
• Non-volatile storage of wiper position  
• Wiper resistance: 70Ω typical  
• Shutdown mode  
• Shutdown current 6.5µA max  
• Power supply: 2.7V to 5.5V  
• 50kΩ or 10kΩ total resistance  
• High reliability  
The DCP can be used as a voltage divider in a wide variety  
of applications including control, parameter adjustments, AC  
measurement and signal processing.  
- Endurance: 1,000,000 data changes per bit per register  
- Register data retention: 50 years @ T < +55°C  
• 14 Lead TSSOP  
Pinout  
• 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.
