Overview
The ADUM6404ARWZ-RL is a quad-channel digital isolator produced by Analog Devices Inc., leveraging the company's iCoupler® technology. This device integrates an isolated DC/DC converter, known as isoPower®, which provides up to 400 mW of regulated, isolated power at either 5.0 V or 3.3 V from a 5.0 V or 3.3 V input supply. This integration eliminates the need for a separate isolated DC/DC converter in low-power, isolated designs. The ADUM6404ARWZ-RL is designed for high-performance data transmission and is particularly suited for industrial and automotive applications due to its high common-mode transient immunity and robust safety and regulatory approvals.
