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.
