ADM3053BRWZ 1Mbps Isolated CAN Transceiver

ElecSuppliers Part Number GuideSep 06, 2026

ADM3053BRWZ is a signal and power isolated CAN physical layer transceiver from Analog Devices. It combines a CAN transceiver, iCoupler isolation technology and an integrated isoPower isolated DC-DC converter in a single 20-lead wide-body SOIC package.

By integrating both signal isolation and isolated power conversion, the device can simplify isolated CAN interface designs while providing galvanic separation between the logic-side circuitry and CAN bus.

Integrated Signal and Power Isolation

A key feature of ADM3053BRWZ is the integration of isolated power conversion with the CAN interface. Unlike a conventional CAN transceiver that requires a separate isolated power supply, the ADM3053 can generate isolated power internally through its integrated isoPower converter.

The signal path uses Analog Devices iCoupler technology to provide isolation between the logic interface and CAN bus. This architecture can reduce component count and PCB area in systems that require an isolated CAN connection.

The device provides 2.5kVrms isolation and is designed for applications where communication signals and power domains need to remain electrically separated.

1Mbps CAN Communication

ADM3053BRWZ supports CAN communication at data rates up to 1Mbps and complies with the ISO 11898 CAN physical-layer standard.

The transceiver operates from a 4.5V to 5.5V supply, with 5V commonly used for the CAN-side supply. Its CANH and CANL interface provides differential communication suitable for industrial control and distributed CAN networks.

The device also incorporates slope control to help reduce electromagnetic emissions. A typical CANH/CANL slew rate of around 7V/µs can be configured under specified operating conditions.

High Common-Mode Transient Immunity

Industrial communication equipment can experience substantial voltage transients between isolated ground domains. ADM3053BRWZ provides a minimum common-mode transient immunity of 25kV/µs, helping maintain signal integrity during fast common-mode voltage changes.

The device also includes thermal shutdown protection and current limiting functions. An unpowered node does not disturb the CAN bus, which is useful in distributed systems where individual nodes may be powered down or disconnected.

Flexible Logic-Side Interface

The logic-side interface supports VIO from 3.0V to 5.5V, allowing the transceiver to connect with a range of digital control circuits.

This makes ADM3053BRWZ suitable for isolated CAN interfaces connected to microcontrollers, industrial processors and embedded control systems without requiring a separate logic-level translator in many 3.3V or 5V designs.

20-Lead Wide-Body SOIC Package

ADM3053BRWZ is supplied in a 20-lead wide-body SOIC package with a nominal body size of approximately 13mm × 7.6mm. The package provides the creepage and clearance needed for the integrated isolation architecture while remaining suitable for standard surface-mount assembly.

The specified operating temperature range is -40°C to +85°C, making the device suitable for industrial environments.

Applications

ADM3053BRWZ can be used in industrial CAN networks, factory automation systems, motor control equipment, building automation, isolated CAN gateways, distributed control systems and other embedded applications that require galvanic isolation.

Its combination of 1Mbps CAN communication, integrated signal and power isolation, high common-mode transient immunity and a single-package implementation makes ADM3053BRWZ a practical option for compact isolated CAN interfaces.
