Overview
The ADM3057EBRWZ-RL, produced by Analog Devices Inc., is a 5 kV rms and 3 kV rms isolated controller area network (CAN) physical layer transceiver. This device integrates an isolated dc-to-dc converter and employs Analog Devices' iCoupler® technology, combining a 3-channel isolator, a CAN transceiver, and an isoPower® dc-to-dc converter into a single, surface-mount, small outline integrated circuit (SOIC) package. It supports flexible data rate (CAN FD) requirements up to 5 Mbps and higher, complying with the ISO 11898-2: 2016 standard. The device is powered by a single 5 V supply, providing a fully isolated solution for CAN and CAN FD applications.
