GENERAL DESCRIPTION
The ADR44x series is a family of XFET voltage references
featuring ultralow noise, high accuracy, and low temperature
drift performance. Using Analog Devices, Inc., patented
temperature drift curvature correction and XFET (eXtra
implanted junction FET) technology, voltage change vs.
temperature nonlinearity in the ADR44x is greatly minimized.
The XFET references offer better noise performance than
buried Zener references, and XFET references operate off
low supply voltage 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 applications.
The ADR44x family has the capability to source up to 10 mA of
output current and sink up to 5 mA. It also comes with a trim
terminal to adjust the output voltage over a 0.5% range without
compromising performance.
Offered in two electrical grades, the ADR44x family is avail-
able in 8-lead MSOP and narrow SOIC packages. All versions
are specified over the extended industrial temperature range of
40°C to +125°C.
