Quad Digitally Controlled Potentiometers (XDCP™)  
Data Sheet  
July 27, 2005  
FN8086.0  
2
Low Noise, Low Power I C® Bus, 256 Taps  
Features  
The ISL90840 integrates four digitally controlled  
potentiometers (XDCP) on a monolithic CMOS integrated  
circuit.  
• Four potentiometers in one package  
• 256 resistor taps - 0.4% resolution  
2
• I C 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  
- Three address pins, up to eight devices/bus  
• Wiper resistance: 70Ω typical @ 3.3V  
• Standby current <5µA max  
2
I C bus interface. Each potentiometer has an associated  
Wiper Register (WR) that can be directly written to and read  
by the user. The contents of the WR controls the position of  
the wiper.  
• Power supply: 2.7V to 5.5V  
• 50kΩ, 10kΩ total resistance  
The DCPs can be used as three-terminal potentiometers or  
as two-terminal variable resistors in a wide variety of  
applications including control, parameter adjustments, and  
signal processing.  
• 20 Lead TSSOP  
• Pb-free plus anneal available (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.
