Overview
The ADUM6404CRWZ-RL is a quad-channel digital isolator produced by Analog Devices Inc., incorporating the company's iCoupler® technology. This device features an integrated, isolated dc-to-dc converter known as isoPower®, which provides regulated, isolated power at either 5.0 V or 3.3 V. It is designed to eliminate the need for a separate isolated power supply, making it a compact and efficient solution for various applications requiring electrical isolation.
