Dual Digitally Controlled Potentiometers (XDCP™) Low Noise, Low Power, I C  
Bus, 128 Taps  
The ISL22326WMVEP integrates two digitally controlled  
potentiometers (XDCP) and non-volatile memory on a  
monolithic CMOS integrated circuit.  
Features  
• Specifications per DLA VID V62/08604-01XE  
• Full Mil-Temp Electrical Performance from -55°C to +125°C  
The digitally controlled potentiometers are implemented with  
a combination of resistor elements and CMOS switches. The  
position of the wipers are controlled by the user through the  
• Controlled Baseline with One Wafer Fabrication Site and  
One Assembly/Test Site  
2
I C bus interface. Each potentiometer has an associated  
• Full Homogeneous Lot Processing in Wafer Fab  
volatile Wiper Register (WR) and a non-volatile Initial Value  
Register (IVR) that can be directly written to and read by the  
user. The contents of the WR controls the position of the  
wiper. At power-up, the device recalls the contents of the two  
DCP’s IVR to the corresponding WRs.  
• No Combination of Wafer Fabrication Lots in Assembly  
• Full Traceability Through Assembly and Test by  
Date/Trace Code Assignment  
• Enhanced Process Change Notification  
• Enhanced Obsolescence Management  
• Eliminates Need for Up-Screening a COTS Component  
• Two Potentiometers in One Package  
• 128 Resistor Taps  
The DCPs can be used as three-terminal potentiometers or  
as two-terminal variable resistors in a wide variety of  
applications including control, parameter adjustments and  
signal processing.

• I C Serial Interface  
The specifications for an Enhanced Product (EP) device are  
defined in a Vendor Item Drawing (VID), which is controlled  
by the Defense Logistics Agency (DLA). “Hot-links” to the  
applicable VID and other supporting application information  
are provided on our website.
