Overview
The ADM3057EBRWZ from Analog Devices Inc. is a highly integrated, isolated controller area network (CAN) physical layer transceiver. This device is designed to meet the flexible data rate (CAN FD) requirements, operating at data rates up to 12 Mbps and complying with the ISO 11898-2:2016 standard. It features an integrated isolated dc-to-dc converter using Analog Devices' isoPower® technology, ensuring complete isolation between the CAN controller and the physical layer bus. This isolation is crucial for applications requiring high safety and reliability standards.
