Overview
The ADM3053BRWZ-REEL7, produced by Analog Devices Inc., is an isolated controller area network (CAN) physical layer transceiver that integrates an isolated dc-to-dc converter. This device complies with the ISO 11898 standard and employs Analog Devices' iCoupler technology to combine a 2-channel isolator, a CAN transceiver, and an isoPower dc-to-dc converter into a single 20-lead, wide-body SOIC package. It provides a fully isolated interface between the CAN protocol controller and the physical layer bus, supporting data rates up to 1 Mbps. The device is powered by a single 5 V supply and features an on-chip oscillator that drives an internal transformer to provide isolated power.
