ADM3053BRWZ-REEL7 Isolated CAN Transceiver

ElecSuppliers Part Number GuideSep 06, 2026

The ADM3053BRWZ-REEL7 is a signal and power isolated CAN transceiver from Analog Devices, combining CAN physical-layer communication, digital isolation and an integrated isolated DC-to-DC converter in a single device. It is designed for CAN networks where galvanic isolation is required between the controller side and the bus side.

With support for data rates up to 1Mbps and compliance with the ISO 11898 standard, the ADM3053 is suited to industrial communication equipment and fieldbus applications.

Integrated Signal and Power Isolation

A key feature of the ADM3053BRWZ-REEL7 is that both CAN signal isolation and isolated power conversion are integrated into the device. Its iCoupler isolation technology separates the logic interface from the CAN bus, while the integrated isoPower circuit provides isolated power for the bus-side circuitry.

The device provides 2.5kV rms signal and power isolation. This architecture can simplify isolated CAN interface designs by reducing the number of separate isolation and power-conversion components required on the PCB.

1Mbps CAN Communication

The ADM3053 supports CAN communication at data rates up to 1Mbps. It provides a standard CAN physical-layer interface with CANH and CANL bus connections and logic-side TXD and RXD signals.

The device operates from a 5V supply on VCC, while the VIO interface supports either 5V or 3.3V operation. This allows the transceiver to interface with different logic-level systems while maintaining isolation between the controller and CAN bus.

Protection and EMC Features

The ADM3053 includes current limiting and thermal shutdown protection for improved robustness during abnormal operating conditions. Its high common-mode transient immunity exceeds 25kV/µs, helping maintain communication across electrically noisy environments.

A slope-control function is also provided to help reduce electromagnetic interference in CAN network designs.

Wide-Body SOIC Package

The ADM3053BRWZ-REEL7 is supplied in a 20-lead wide-body SOIC package. The surface-mount package is suitable for automated PCB assembly and provides the physical separation required for the isolated interface.

The REEL7 suffix identifies the tape-and-reel ordering version, making it suitable for volume surface-mount production.

Industrial CAN Network Applications

ADM3053BRWZ-REEL7 is well suited to isolated CAN interfaces used in industrial field networks, automation equipment, distributed control systems and other systems where the CAN bus operates in an electrically different environment from the main controller.

By combining the transceiver, signal isolation and isolated DC-to-DC power conversion, the device can help simplify the architecture of an isolated CAN communication interface.

PCB Design Considerations

The integrated isoPower converter uses high-frequency switching to transfer power across the isolation barrier. PCB layout therefore plays an important role in controlling radiated emissions and maintaining reliable operation.

Designers should pay particular attention to isolation spacing, power-supply bypassing and the physical routing around the isolation barrier. The specified operating temperature range of -40°C to +85°C also makes the device suitable for many industrial environments.

For designs requiring a compact isolated CAN interface with integrated isolated power, 1Mbps communication capability and a 2.5kV rms isolation rating, the ADM3053BRWZ-REEL7 provides a highly integrated solution.
