Overview
The ADUM6402ARWZ is a quad-channel digital isolator produced by Analog Devices, Inc. This device integrates an isolated DC-to-DC converter using the isoPower® technology, which is based on the iCoupler® chip scale transformer technology. This integration eliminates the need for a separate isolated DC-to-DC converter in low-power, isolated designs. The ADUM6402ARWZ 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, respectively. It is designed for high reliability and compliance with various safety standards, including UL recognition and VDE certification.
