ADM3050EBRIZ

Overview

The ADM3050EBRIZ is a 5.7kV rms signal isolated CAN FD transceiver manufactured by Analog Devices Inc. It supports data rates up to 12 Mbps and complies with ISO 11898-2:2016. The device integrates a 2-channel isolator and CAN transceiver in an SOIC-8 package using iCoupler technology. Electrical specifications include a logic supply range of 1.7 V to 5.5 V, a bus supply range of 4.5 V to 5.5 V, and a maximum loop propagation delay of 150 ns. It features an extended common-mode range of ±25 V, bus fault protection of ±40 V, and operates within a temperature range of −40°C to +125°C.

Feature Summary

• Provides 5.7 kV rms reinforced insulation between the logic side and the CAN bus side.
• Supports CAN flexible data rate (CAN FD) protocols with data rates up to 12 Mbps.
• Features dominant timeout functionality to prevent bus lockup during fault conditions.
• Includes ±40 V miswire protection on CANH and CANL pins against accidental connection to +24 V bus supplies.

Applications

• CANOpen, DeviceNet, and other CAN bus implementations
• Industrial automation systems
• Process control and building control networks
• Transportation and infrastructure applications

Procurement Notes

Verify the specific ordering suffix 'RIZ' against the manufacturer's current documentation to confirm the exact packaging configuration and reel specifications. Ensure that the procurement channel provides valid traceability for safety-certified components. Confirm compliance with RoHS directives and moisture sensitivity levels prior to finalizing orders.

Selection Notes

Select this component when high-voltage isolation is required between the controller and the physical layer bus. The device accommodates standard 1.8 V, 2.5 V, 3.3 V, or 5.0 V CMOS logic levels. Consider the ±25 V common-mode range for environments with significant ground potential differences. Verify thermal dissipation requirements based on the PCB layout and ambient operating conditions.

Part Context

The ADM3050E series utilizes Analog Devices iCoupler technology to integrate digital isolation and transceiver functions into a single surface-mount package. This design eliminates the need for external isolation components, reducing board space and simplifying the schematic. The family is designed to meet stringent safety standards including UL 1577 and VDE certifications for reinforced insulation.
