FEATURES  
DESCRIPTION  
• Four potentiometers in one package  
• 256 resistor taps/pot–0.4% resolution  
• SPI serial interface  
The X9250 integrates  
potentiometers (XDCP) on a monolithic CMOS  
integrated circuit.  
4
digitally controlled  
• Wiper resistance, 40Ω typical @ V  
= 5V  
CC  
The digitally 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 4 nonvolatile Data Registers (DR0:DR3)  
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. Power  
up recalls the contents of DR0 to the WCR.  
• Four nonvolatile data registers for each pot  
• Nonvolatile storage of wiper position  
• Standby current < 5µA max (total package)  
• Power supplies  
—V  
= 2.7V to 5.5V  
CC  
—V+ = 2.7V to 5.5V  
—V– = -2.7V to -5.5V  
• 100KΩ, 50KΩ total pot resistance  
• High reliability  
—Endurance – 100,000 data changes per bit per  
register  
—Register data retention – 100 years  
• 24-lead SOIC, 24-lead TSSOP, 24-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.  
• Dual supply version of X9251
