Low Noise/Low Power/2-Wire Bus  
Data Sheet

DESCRIPTION  
Dual Digitally Controlled Potentiometers  
(XDCP™)  
The X9418 integrates two digitally controlled  
potentiometers (XDCP) on a monolithic CMOS  
integrated microcircuit.  
FEATURES  
• Two potentiometers in one package  
• 2-wire serial interface  
• Register oriented format  
—Direct Read/Write/Transfer Wiper Position  
—Store as many as Four Positions per  
Potentiometer  
The digitally controlled potentiometer is implemented  
using 63 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 through the switches. Power up recalls  
the contents of DR0 to the WCR.  
• Power supplies  
—V  
= 2.7V to 5.5V  
CC  
—V+ = 2.7V to 5.5V  
—V– = -2.7V to -5.5V  
• Low power CMOS  
—Standby current < 1µA  
—Ideal for Battery Operated Applications  
• High reliability  
The XDCP can be used as  
a three-terminal  
Endurance–100,000 Data Changes per Bit per  
Register  
potentiometer or as a two-terminal variable resistor in  
a wide variety of applications including control,  
parameter adjustments, and signal processing.  
—Register Data Retention–100 years  
• 8-bytes of nonvolatile memory  
• 2.5k, 10kresistor array  
• Resolution: 64 taps each potentiometer  
• 24-pin plastic DIP, 24-lead TSSOP and 24-lead  
SOIC packages
