Dual Digitally-Controlled (XDCPTM) Potentiometers  
FEATURES  
DESCRIPTION  
• Dual–Two separate potentiometers  
• 256 resistor taps/pot–0.4% resolution  
• 2-Wire Serial Interface for write, read, and  
transfer operations of the potentiometer  
• Wiper Resistance, 100Ω typical @ V+ = 5V, V- = -5V  
• 16 Nonvolatile Data Registers for Each  
Potentiometer  
• Nonvolatile Storage of Multiple Wiper Positions  
• Power On Recall. Loads Saved Wiper Position on  
Power Up.  
The X9268 integrates  
potentiometer (XDCP) on  
integrated circuit.

digitally controlled  
monolithic CMOS  
a
The digital 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  
2-Wire bus interface. Each potentiometer has  
associated with it a volatile Wiper Counter Register  
(WCR) and a four nonvolatile Data Registers 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. Powerup  
recalls the contents of the default Data Register (DR0)  
to the WCR.  
• Standby Current < 5µA Max  
• V : 2.7V to 5.5V Operation  
CC  
• 50KΩ, 100KΩ versions of End to End Pot  
Resistance  
• Endurance: 100,000 Data Changes per Bit per  
Register  
• 100 yr. Data Retention  
• 24-Lead SOIC, 24-Lead XBGA  
• 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.
