Preliminary Information  
X9409  
Quad Digitally Controlled Potentiometers (XDCP™)  
FEATURES  
DESCRIPTION  
• Four potentiometers per package  
• 64 resistor taps  
The X9409 integrates  
potentiometers (XDCP) on a monolithic CMOS  
integrated microcircuit.  
4
digitally controlled  
• 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.  
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.  
• Standby current < 1µA typical  
• System V : 2.7V to 5.5V operation  
CC  
• 10KΩ, 2.5KΩ End to end resistance  
• 100 yr. data retention  
• Endurance: 100,000 data changes per bit per  
register  
• Low power CMOS  
• 24-lead SOIC, 24-lead TSSOP, and  
24-lead CSP (Chip Scale Package) 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.
