ADR431ARZ Datasheet PDF - ADI

●GENERAL DESCRIPTION

●The ADR43x series is a family of XFET voltage references featuring low noise, high accuracy, and low temperature drift performance. Using ADI’s patented temperature drift curvature correction and XFET (eXtra implanted junction FET) technology, the ADR43x’s voltage change versus temperature nonlinearity is minimized.
