ADM3055EBRIZ

Overview

The ADM3055EBRIZ is a 5kV isoPower isolated CAN-FD transceiver manufactured by Analog Devices Inc. It integrates an On-Off Keying (OOK) signal isolation channel and an isoPower DC-DC converter within a single SOIC-20 package. The device supports data rates up to 12 Mb/s, complying with ISO 11898-2:2016 for CAN FD networks. It operates on a supply voltage ranging from 500 mV to 6 V, with a maximum operating current of 177 mA. The component functions reliably across a temperature range of -40°C to +105°C and includes ESD protection rated at 4 kV.

Feature Summary

• Integrates logic side OOK signal isolation channels and an isoPower DC-DC converter for regulated isolated power generation.
• Provides complete signal and power isolation suitable for CAN and CAN FD applications.
• Delivers isolated power output that remains well below EN55022 Class B emission limits when used with ferrites on a 2-layer PCB.

Applications

• Controller Area Network (CAN) networks
• CAN with Flexible Data Rate (CAN FD) networks
• Industrial automation systems
• Process control and building control infrastructure

Procurement Notes

Verify the specific suffix 'IZ' against the manufacturer's official datasheet to confirm RoHS compliance and lead-free status. Confirm the SOIC-20 package dimensions and pinout configuration match the design requirements. Check for humidity sensitivity classification and required reflow soldering profiles prior to assembly. Ensure the evaluation board EVAL-ADM3055EEBZ is available for functional testing if necessary.

Selection Notes

Select this component for designs requiring high-voltage isolation between the microcontroller and the CAN bus without external isolation transformers. The integrated isoPower converter simplifies bill of materials by eliminating separate isolated power supplies. Verify that the 12 Mb/s data rate meets the network speed requirements and that the 500 mV minimum supply voltage aligns with the system's low-power operational needs.

Part Context

The ADM3055EBRIZ belongs to the ADM3055E series of isolated CAN transceivers. It utilizes Analog Devices' iCoupler technology to combine digital isolation and power conversion in a compact form factor. This series is designed to replace traditional transformer-based isolation solutions, offering reduced size and simplified layout for automotive and industrial communication interfaces.
