X9241  
Quad Digitally Controlled Potentiometer (XDCP™)  
FEATURES  
DESCRIPTION  
• Four potentiometers in one package  
• 2-wire serial interface  
• Register oriented format  
The X9241 integrates four digitally controlled  
potentiometers (XDCP) on a monolithic CMOS  
integrated microcircuit.  
—Direct read/write/transfer of wiper positions  
—Store as many as four positions per  
potentiometer  
• Terminal Voltages: ±5V  
• Cascade resistor arrays  
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.  
• Low power CMOS  
• High Reliability  
—Endurance–100,000 data changes per bit per  
register  
—Register data retention–100 years  
• 16-bytes of nonvolatile memory  
• 3 resistor array values  
—2KΩ to 50KΩ mask programmable  
—Cascadable for values of 500Ω to 200KΩ  
• Resolution: 64 taps each pot  
• 20-lead plastic DIP, 20-lead TSSOP and 20-lead  
SOIC packages  
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.
