Analog Devices Inc. ADM3055E & ADM3057E Isolated CAN Transceivers

Analog Devices Inc. ADM3055E and ADM3057E Isolated CAN Transceivers are 5kVrms and 3kVrms isolated controller area network (CAN) physical layer transceivers with integrated isolated DC-to-DC converters. Analog Devices ADM3055E and ADM3057E support data rates as high as 12Mbps. The devices use iCoupler® technology to combine a 3-channel isolator, a CAN transceiver, and an isoPower® dc-to-dc converter into a single, SMD, small outline integrated circuit (SOIC) package. The CAN Transceivers are powered by a single 5V supply, realizing a fully isolated solution for CAN and CAN FD. The devices offer complete isolation between the CAN controller and the physical layer bus.

The Analog Devices Inc. ADM3055E provides 5kVrms isolation voltage, a 10kV surge test, and 8.3mm creepage and clearance to ensure the device meets application reinforced isolation requirements. The ADM3057E has an isolation voltage of 3kVrms and 7.8mm creepage in a 20-lead, wide-body SOIC. The ADM3055E and ADM3057E Transceivers are fully specified over an industrial temperature range of -40°C to +105°C.
