Single Supply/Low Power/256-Tap/2-Wire Bus Quad Digitally-Controlled  
(XDCP™) Potentiometers  
The X9259 integrates four digitally controlled potentiometers  
Features  
(XDCP) on a monolithic CMOS integrated circuit.  
• Four separate potentiometers in one package  
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-wire bus interface. Each potentiometer has associated with  
it a volatile Wiper Counter Register (WCR) and four nonvolatile  
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.  
• 256 resistor taps–0.4% resolution  
• 2-wire serial interface for write, read, and  
transfer operations of the potentiometer  
• Wiper resistance: 100Ω typical at V = 5V  
CC  
• 4 nonvolatile data registers for each potentiometer  
• Nonvolatile storage of multiple wiper positions  
• Standby current <5µA max  
• V : 2.7V to 5.5V operation  
CC  
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.  
• 50kΩ version of total resistance  
• Endurance: 100,000 data changes per bit per register  
• 100 year data retention  
• Single supply version of X9258  
• 24 Ld SOIC, 24 Ld TSSOP  
• Low power CMOS  
• Pb-Free (RoHS compliant)
