Dual Digitally-Controlled (XDCPTM) Potentiometers  
FEATURES  
DESCRIPTION  
• Dual–Two Separate Potentiometers  
• 256 resistor taps/pot–0.4% resolution  
• SPI Serial Interface for write, read, and transfer  
operations of the potentiometer  
• Wiper Resistance, 100Ω typical @ V+ = 5V,V- = -5V  
• 4 Nonvolatile Data Registers for Each  
Potentiometer  
• Nonvolatile Storage of Multiple Wiper Positions  
• Power On Recall. Loads Saved Wiper Position on  
Power Up.  
The X9261 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 SPI bus  
interface. Each potentiometer has associated with it a  
volatile Wiper Counter Register (WCR) and a four  
nononvolatile 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 Resistance  
• 100 yr. Data Retention  
• Endurance: 100,000 Data Changes per Bit per  
Register  
• 24-Lead SOIC, 24-Lead XBGA  
• Low Power CMOS  
The XDCP can be used as  
a three-terminal  
• Power Supply V  
= 2.7V to 5.5V  
potentiometer or as a two terminal variable resistor in  
a wide variety of applications including control,  
parameter adjustments, and signal processing.
