GENERAL DESCRIPTION

The ADR441-EP1 is a XFET® voltage reference featuring ultralow noise, high accuracy, and low temperature drift performance. Using Analog Devices, Inc., temperature drift curvature correction and extra implanted junction FET (XFET) technology, voltage change vs. temperature nonlinearity in the ADR441-EP is greatly minimized.

The XFET reference offers better noise performance than buried Zener references, and the XFET reference operates off
low supply voltage headroom (500 mV). This combination of features makes the ADR441-EP ideally suited for precision signal conversion applications in high end data acquisition systems, military communication, and avionics applications.
