X9258  
®
Low Noise/Low Power/2-Wire Bus/256 Taps  
Data Sheet  
May 6, 2005  
FN8168.1  
DESCRIPTION  
The X9258 integrates  
potentiometers (XDCP) on a monolithic CMOS  
integrated circuit.  
Quad Digital Controlled Potentiometers  
(XDCP™)  
4
digitally controlled  
FEATURES  
• Four potentiometers in one package  
• 256 resistor taps/pot–0.4% resolution  
• 2-wire serial interface  
• Wiper resistance, 40Ω typical @ V+ = 5V, V- = -5V  
• Four nonvolatile data registers for each pot  
• Nonvolatile storage of wiper position  
• Standby current < 5µA max (total package)  
• Power supplies  
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  
2-wire 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.  
—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  
• Dual supply version of X9259  
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.
