Overview
The ADuM5200WCRWZ is a dual-channel digital isolator with an integrated, isolated dc-to-dc converter, developed by Analog Devices Inc. This device utilizes the iCoupler® technology, which combines logic signal isolation with a magnetic-based dc-to-dc converter. This integration eliminates the need for a separate isolated dc-to-dc converter in low-power isolated designs, providing a compact and efficient solution. The ADuM5200WCRWZ is designed for high reliability and safety, with features such as high temperature operation up to 105°C and high common-mode transient immunity.
