ADR443ARZ

The ADR443 series ultralow noise Voltage Reference features high accuracy and low temperature drift performance. Using 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® reference offers better noise performance than buried zener references and XFET® reference operate off low supply voltage headroom (0.5V). This combination of features makes the ADR44x family ideally suited for precision signal conversion applications in high-end data acquisition systems and optical networks applications. The ADR44x family has the capability to source up to 10mA of output current and sink up to -5mA. It also comes with a trim terminal to adjust the output voltage over a 0.5% range without compromising performance.
