®
Low Noise/Low Power/SPI Bus/256 Taps  
Data Sheet  
August 29, 2006  
FN8165.3  
DESCRIPTION  
The X9250 integrates  
Quad Digitally Controlled Potentiometers  
(XDCP™)  
4
digitally controlled  
potentiometers (XDCP) on a monolithic CMOS  
integrated circuit.  
FEATURES  
• Four potentiometers in one package  
• 256 resistor taps/pot - 0.4% resolution  
• SPI serial interface  
The digitally controlled potentiometer is implemented  
using 255 resistive elements in a series array.  
Between each element are tap points connected to the  
wiper terminal through switches. The position of the  
wiper on the array is controlled by the user through the  
SPI bus interface. Each potentiometer has associated  
with it a volatile Wiper Counter Register (WCR) and 4  
nonvolatile Data Registers (DR0:DR3) that can be  
directly written to and read by the user. The contents  
of the WCR controls the position of the wiper on the  
resistor array though the switches. Power up recalls  
the contents of DR0 to the WCR.  
• Wiper resistance, 40Ω typical @ V  
= 5V  
CC  
• Four nonvolatile data registers for each pot  
• Nonvolatile storage of wiper position  
• Standby current < 5µA max (total package)  
• Power supplies  
—V  
= 2.7V to 5.5V  
CC  
—V+ = 2.7V to 5.5V  
—V– = -2.7V to -5.5V  
• 100kΩ, 50kΩ total pot resistance  
• High reliability  
—Endurance – 100,000 data changes per bit per  
register  
—Register data retention - 100 years  
• 24 Ld SOIC, 24 Ld TSSOP  
• Dual supply version of X9251  
• Pb-free plus anneal available (RoHS compliant)  
The XDCP can be used as a three-terminal  
potentiometer or as a two-terminal variable resistor in  
a wide variety of applications including control,  
parameter adjustments, and signal processing.
