Overview
The ADR435BRMZ is a part of the ADR435 series, a family of XFET® voltage references from Analog Devices Inc. These devices are known for their low noise, high accuracy, and low temperature drift performance. The ADR435 series utilizes Analog Devices' temperature drift curvature correction and extra implanted junction FET (XFET) technology to minimize voltage change vs. temperature nonlinearity. This results in a low noise solution suitable for 5V systems, operating at lower current (800µA) and lower supply voltage headroom (2V) compared to buried zener references.
