Overview
The ADUM6401CRWZ-RL is a quad-channel digital isolator produced by Analog Devices Inc., featuring the innovative isoPower® integrated, isolated DC-to-DC converter. This device is based on Analog Devices' iCoupler® technology, which enables the DC-to-DC converter to provide 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-to-DC converter in low-power, isolated designs. The ADUM6401CRWZ-RL is designed for high reliability and safety, with approvals from UL, VDE, and other regulatory bodies, making it suitable for a wide range of applications.
