X9251  
®
Single Supply/Low Power/256-Tap/SPI Bus  
Data Sheet  
April 13, 2007  
FN8166.5  
Quad Digitally-Controlled (XDCP™)  
Potentiometer  
Features  
• Four potentiometers in one package  
The X9251 integrates four digitally controlled potentio-  
meters (XDCP) on a monolithic CMOS integrated circuit.  
• 256 resistor taps–0.4% resolution  
• SPI Serial Interface for write, read, and transfer operations  
of the potentiometer  
The digitally controlled potentiometers are imple-mented  
with a combination of resistor elements and CMOS switches.  
The position of the wipers are controlled by the user through  
the SPI bus interface. Each potentiometer has associated  
with it a volatile Wiper Counter Register (WCR) and four  
non-volatile Data Registers that can be directly written to and  
read by the user. The content of the WCR controls the  
position of the wiper. At power-up, the device recalls the  
content of the default Data Registers of each DCP (DR00,  
DR10, DR20, and DR30) to the corresponding WCR.  
• Wiper resistance: 100Ω typical @ V  
CC  
= 5V  
• 4 Non-volatile data registers for each  
potentiometer  
• Non-volatile storage of multiple wiper positions  
• Standby current <5µA max  
• V : 2.7V to 5.5V Operation  
CC  
• 50kΩ, 100kΩ versions of total resistance  
• 100 year data retention  
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.  
• Single supply version of X9250  
• Endurance: 100,000 data changes per bit per register  
• 24 Ld SOIC, 24 Ld TSSOP  
• Low power CMOS  
• Pb-free plus anneal available (RoHS compliant)
