Overview
The ADUM6403CRWZ is a quad-channel digital isolator produced by Analog Devices Inc. This device integrates an isolated DC/DC converter using Analog Devices' iCoupler® technology. It 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. This integration eliminates the need for a separate isolated DC/DC converter in low-power, isolated designs. The device is packaged in a 16-lead SOIC wide body package and is designed for high common-mode transient immunity and high temperature operation up to 105°C.
