Overview
The ADR435ARMZ is a part of the ADR430/ADR431/ADR433/ADR434/ADR435 series, a family of XFET voltage references developed by Analog Devices Inc. These voltage references are known for their low noise, high accuracy, and low temperature drift performance. Utilizing Analog Devices' patented temperature drift curvature correction and extra implanted junction FET (XFET) technology, these references minimize voltage change vs. temperature nonlinearity. The ADR435ARMZ operates at lower current and supply voltage headroom compared to traditional buried Zener references, making it an ideal solution for 5 V systems.
