DESCRIPTION  
Quad Digitally-Controlled (XDCP™)  
Potentiometer  
The X9251 integrates four digitally controlled potentio-  
meters (XDCP) on a monolithic CMOS integrated  
circuit.  
FEATURES  
• Four potentiometers in one package  
• 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: 100typical @ V  
= 5V  
CC  
• 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  
• 50k, 100kversions of total resistance  
• 100 yr. data retention  
• Single supply version of X9250  
• Endurance: 100,000 data changes per bit per  
register  
• 24 Ld SOIC, 24 Ld TSSOP  
• Low power CMOS  
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.  
• Pb-free plus anneal available (RoHS compliant)
