Overview
The ADUM5402WCRWZ-1RL, produced by Analog Devices Inc., is a quad-channel digital isolator that integrates an isolated DC-to-DC converter using the isoPower technology. This device is part of the ADuM5400 series and is designed to eliminate the need for a separate isolated DC-to-DC converter in low-power isolated designs. It utilizes the iCoupler chip scale transformer technology to isolate logic signals and provide up to 500 mW of regulated, isolated power at 5.0 V. The device is packaged in a 16-lead SOIC package and is suitable for high-temperature operation up to 105°C.
