Low Noise/Low Power/SPI Bus Quad Digitally Controlled Potentiometers  
(XDCP™)  
FEATURES  
DESCRIPTION  
• Four potentiometers per package  
• 64 resistor taps  
The X9400 integrates four digitally controlled  
potentiometers (XDCPs) on a monolithic CMOS  
integrated circuit.  
• SPI serial interface for write, read, and transfer  
operations of the potentiometer  
• Wiper resistance, 40typical 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 SPI  
serial bus interface. Each potentiometer has  
associated with it a volatile Wiper Counter Register  
(WCR) and four nonvolatile Data Registers (DR0-3)  
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 max  
• System V : 2.7V to 5.5V operation  
CC  
+
• Analog V /V : -5V to +5V  
• 10k, 2.5kend to end resistance  
• 100 yr. data retention  
• Endurance: 100,000 data changes per bit per  
register  
• Low power CMOS  
• 24 Ld SOIC and 24 Ld TSSOP  
• Pb-free plus anneal available (RoHS compliant)  
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.
