Product Introduction

Overview

The ADuM3123ARZ-RL7, produced by Analog Devices Inc., is a 4.0 A isolated, single-channel driver that utilizes iCoupler® technology to provide precision isolation. This component is housed in a narrow-body, 8-lead SOIC package and offers 3000 V rms isolation. It combines high-speed CMOS and monolithic transformer technology, providing superior performance compared to traditional alternatives such as pulse transformers and gate drivers. The ADuM3123 operates with an input supply ranging from 3.0 V to 5.5 V, making it compatible with lower voltage systems, and ensures true galvanic isolation between the input and output, allowing the output to operate continuously up to 380 V rms relative to the input.
