Product Introduction

Overview

The ADR433ARMZ is a three-terminal voltage reference IC from Analog Devices Inc., designed to provide a precise and stable output voltage. It is part of the ADR430/ADR431/ADR433/ADR434/ADR435 series, which features low noise, high accuracy, and low temperature drift performance. This series utilizes Analog Devices' temperature drift curvature correction and extra implanted junction FET (XFET) technology to minimize voltage change vs. temperature nonlinearity.

The ADR433ARMZ operates at a lower current (800 μA) and lower supply voltage headroom (2 V) compared to buried Zener references, making it a low noise solution for 5 V systems. It is available in 8-lead MSOP and 8-lead narrow SOIC packages and is specified over the extended industrial temperature range of −40°C to +125°C.
