Overview
The ADR435BRZ-REEL7 is a part of the ADR435 series, a family of XFET® voltage references developed by Analog Devices Inc. These voltage references are renowned for their low noise, high accuracy, and minimal temperature drift performance. Utilizing Analog Devices' temperature drift curvature correction and extra implanted junction FET (XFET) technology, the ADR435BRZ-REEL7 minimizes voltage change vs. temperature nonlinearity. This device operates at lower current (800µA) and lower supply voltage headroom (2V) compared to traditional buried zener references, making it an ideal solution for 5V systems.
