GENERAL DESCRIPTION ADR445ARMZ

The ADR440/ADR441/ADR443/ADR444/ADR4451 series is a family of XFET® voltage references 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 ADR440/ADR441/ ADR443/ADR444/ADR445 is greatly minimized.
