GENERAL DESCRIPTION  
Offered in two electrical grades, the ADR44x family is avail-  
able in the 8-lead SOIC and MSOP packages. All versions  
are specified over the extended industrial temperature range  
(−40oC to +125oC).  
The ADR44x series is a family of XFET® voltage references  
featuring ultralow noise, high accuracy, and low temperature  
drift performance. Using ADI’s patented temperature drift  
curvature correction and XFET (eXtra implanted junction FET)  
technology, the ADR44x family’s voltage change vs. temperature  
nonlinearity is greatly minimized.

The XFET references offer better noise performance than  
buried-Zener references, and XFET references operate off  
low supply headroom (0.5 V). This combination of features  
makes the ADR44x family ideally suited for precision signal  
conversion applications in high-end data acquisition systems,  
optical networks, and medical requirements.  
The ADR44x family has the capability to source up to 10 mA  
and sink up to 5 mA of output current. It also comes with a  
TRIM terminal to adjust the output voltage over a 0.5% range  
without compromising any performance.
