FN8096.0  
PRELIMINARY  
Low Noise, Low Power, I C Bus,  
256 Taps  
Features  
• Four potentiometers in one package  
The ISL90842 integrates four digitally controlled  
potentiometers (XDCP) on a monolithic CMOS integrated  
circuit.  
• 256 resistor taps–0.4% resolution  
2
• I C serial interface  
• Wiper resistance: 70Ω typical @ 3.3V  
• Standby current <5µA max  
• Power supply: 2.7V to 5.5V  
• 50kΩ, 10kΩ total resistance  
• 14 Lead TSSOP  
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  
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.  
Pinout  
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.
