Overview
The ADUM5240ARZ-RL7, produced by Analog Devices Inc., is a dual-channel digital isolator that integrates isoPower® technology for isolated power conversion. This component utilizes Analog Devices' iCoupler® technology, which employs chip-scale transformers for both logic signal isolation and power conversion. The ADUM5240ARZ-RL7 provides up to 50 mW of regulated, isolated power at 5 V, eliminating the need for a separate isolated dc-to-dc converter in low-power isolated designs. It is packaged in a narrow-body, 8-lead SOIC and is RoHS compliant, making it suitable for a variety of applications requiring high isolation and reliability.
