Single Supply/Low Power/256-Tap/SPI Bus  
Data Sheet  
February 28, 2005  
FN8171.0  
DESCRIPTION  
Dual Digitally-Controlled (XDCP™)  
Potentiometers  
The X9261 integrates  
potentiometer (XDCP) on  
integrated circuit.  
2
digitally controlled  
monolithic CMOS  
a
FEATURES  
• Dual–Two Separate Potentiometers  
• 256 resistor taps/pot–0.4% resolution  
• SPI Serial Interface for write, read, and transfer  
operations of the potentiometer single supply  
device  
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  
four non-volatile 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.  
• Wiper Resistance, 100Ω typical @ V  
= 5V  
CC  
• 4 Nonvolatile Data Registers for Each  
Potentiometer  
• Nonvolatile Storage of Multiple Wiper Positions  
• Power-on Recall Loads Saved Wiper Position on  
Power-up.  
• Standby Current < 5µA Max  
• 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 TSSOP, 16-Lead CSP  
(Chip Scale Package)  
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.  
• Low Power CMOS  
• Power Supply V  
= 2.7V to 5.5V
