X9409  
®
Low Noise/Low Power/2-Wire Bus  
Data Sheet  
October 19, 2005  
FN8192.3  
PRELIMINARY  
DESCRIPTION  
Quad Digitally Controlled Potentiometers  
(XDCP™)  
The X9409 integrates  
potentiometers (XDCP) on a monolithic CMOS  
integrated microcircuit.  
4
digitally controlled  
FEATURES  
• Four potentiometers per package  
• 64 resistor taps  
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.  
• 2-wire serial interface for write, read, and trans-  
fer operations of the potentiometer  
• 50Ω Wiper resistance, typical at 5V.  
• Four non-volatile data registers for each  
potentiometer  
• Non-volatile storage of multiple wiper position  
• Power-on recall. Loads saved wiper position on  
power-up.  
• Standby current < 1µA typical  
• System V : 2.7V to 5.5V operation  
CC  
• 10kΩ, 2.5kΩ End to end resistance  
• 100 yr. data retention  
The XDCP can be used as  
a three-terminal  
• Endurance: 100,000 data changes per bit per  
register  
• Low power CMOS  
potentiometer or as a two-terminal variable resistor in  
a wide variety of applications including control,  
parameter adjustments, and signal processing.  
• 24 Ld SOIC, 24 Ld TSSOP  
• Pb-free plus anneal available (RoHS compliant)
