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. Applications Precision data acquisition systems High resolution data converters Battery-powered instrumentation Portable medical instruments Industrial process control systems Precision instruments Optical control circuits Data Sheet, Rev.
