ADM3055 Isolated CAN Transceivers

Analog Devices’ ADM3055 transceivers for industrial automation, process, and building control

Image of Analog Devices' ADM3055 Isolated CAN TransceiversADI’s ADM3055 is a 5 kVRMS isolated controller area network (CAN) physical layer transceiver. This transceiver comes with iCoupler® technology to combine a 3-channel isolator, a CAN transceiver, and isoPower® dc-to-dc converter. The ADM3055E meets CAN flexible data (FD) rate requirements for operation to 5 Mbps and higher, and complies with the ISO 11898-2 standard.

The ADM3055 is powered by a single 5 V supply realizing a fully isolated solution for CAN and CAN FD applications. Radiated emissions from the high-frequency switching of the dc-to-dc converter are kept below EN 55022 Class B limits by continuous adjustments to the switching frequency. This transceiver provides complete isolation between the CAN controller and physical layer bus.

Low propagation delays through the isolation support longer bus cables. Slope control mode is available for standard CAN at low data rates. Standby mode minimizes power consumption when the bus is idle or if the node goes offline. Silent mode allows the TXD input to be ignored for listen-only.

Dominant timeout functionality protects against bus lock up in a fault condition. The current limiting and thermal shutdown features protect against output short circuits. The transceiver is fully specified over an industrial temperature range of -40°C to +105°C and comes in a 20-pin SOIC package. The ADM3055 is ideal for industrial automation, process, and building control.
