Overview
The ADM3053BRWZ is an isolated controller area network (CAN) physical layer transceiver produced by Analog Devices Inc. This device integrates a 2-channel isolator, a CAN transceiver, and an isolated dc-to-dc converter using Analog Devices' iCoupler technology. It is designed to provide a fully isolated CAN solution, making it suitable for applications requiring high isolation and reliability.
The ADM3053BRWZ operates with a single 5 V supply and supports both 5 V and 3.3 V operations on the VIO pin. It complies with the ISO 11898 standard and supports high-speed data rates of up to 1 Mbps. The device is particularly useful in automotive and industrial environments where isolation and robust communication are critical.
