The ADM3050E is a 5.7 kV rms isolated controller area network (CAN) physical layer transceiver with a high performance, basic feature set. The ADM3050E fully meets the CAN flexible data rate (CAN FD) ISO 11898-2:2016 requirements and is further capable of supporting data rates as high as 12 Mbps.
The device employs Analog Devices, Inc., iCoupler® technology to combine a 2-channel isolator and a CAN transceiver into a single small outline integrated circuit (SOIC) surface-mount package. The ADM3050E is a fully isolated solution for CAN and CAN FD applications. The ADM3050E provides isolation between the CAN controller and physical layer bus. Safety and regulatory approvals (pending) for a 5.7 kV rms withstand voltage, an 849 VPEAK working voltage, and a 12.8 kV surge test, ensure that the ADM3050E meets application isolation requirements.
Low loop propagation delays and the extended common-mode range of ±25 V support robust communication on longer bus cables. Dominant timeout functionality protects against bus lock up in a fault condition, and current limiting and thermal shutdown features protect against output short circuits. The CAN bus input and output pins are protected to ±40 V against accidental connection to a +24 V bus supply. The device is fully specified over the −40°C to +125°C industrial temperature range.

Evaluation Kits (1)
The EVAL-ADM3050EEBZ allows the user to evaluate the ADM3050E isolated signal and power transceiver for controller area network (CAN) or CAN with flexible data rate (CAN FD) networks. The EVAL-ADM3050EEBZ allows all of the input and output functions to work without the need for external components.
Based on the Analog Devices, Inc., iCoupler® technology, the ADM3050E integrates logic side on-off keying (OOK) signal isolation channels and an Analog Devices isoPower® dc-to-dc converter to provide regulated, isolated power that is well below CISPR22/EN55022 Class B limits when transmitting on a 2-layer printed circuit board (PCB) with ferrites.
The EVAL-ADM3050EEBZ comes populated with an ADM3050E.
Full specifications of the ADM3050E can be found in the ADM3050E data sheet, available from Analog Devices, Inc., and must be consulted in conjunction with this user guide when using the EVAL-ADM3050EEBZ.
