Overview
The ADM3050EBRIZ-RL is a 5.7 kV rms isolated controller area network (CAN) physical layer transceiver produced by Analog Devices Inc. This device is designed to meet the CAN flexible data rate (CAN FD) ISO 11898-2:2016 requirements and supports data rates up to 12 Mbps. It combines a 2-channel isolator and a CAN transceiver into a single small outline integrated circuit (SOIC) surface-mount package, utilizing Analog Devices' iCoupler® technology. The ADM3050EBRIZ-RL provides full isolation between the CAN controller and the physical layer bus, ensuring robust communication and safety in various industrial applications.
