Overview
The ADUM5401WCRWZ-1, 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 based on Analog Devices' iCoupler® chip scale transformer technology, which isolates logic signals and provides magnetic components for the DC-to-DC converter. This integration eliminates the need for a separate isolated DC-to-DC converter in low-power, isolated designs. The ADUM5401WCRWZ-1 is packaged in a 16-lead SOIC-W package and is qualified for high-temperature operation up to 105°C, making it suitable for various demanding applications.
