Quad Digitally-Controlled (XDCPTM) Potentiometers  
FEATURES  
DESCRIPTION  
• Four separate potentiometers in one package  
• 256 resistor taps–0.4% resolution  
• 2-Wire Serial Interface for write, read, and  
transfer operations of the potentiometer  
The X9259 integrates four digitally controlled potentio-  
meters (XDCP) on a monolithic CMOS integrated  
circuit.  
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 2-wire 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  
• 4 Non-volatile Data Registers for Each  
Potentiometer  
• Non-volatile Storage of Multiple Wiper Positions  
• Standby Current < 5µA Max  
= 5V

• V : 2.7V to 5.5V Operation

• 50K, 100Kversions of Total Resistance  
• Endurance: 100,000 Data Changes per Bit per  
Register  
• 100 yr. Data Retention  
• Single Supply Version of X9258  
• 24-Lead SOIC, 24-Lead TSSOP, 24-Lead CSP  
(Chip Scale Package)  
The XDCP can be used as  
a three-terminal  
• Low Power CMOS  
potentiometer or as a two terminal variable resistor in  
a wide variety of applications including control,  
parameter adjustments, and signal processing.
