ADM2567EBRNZ

Overview

The ADM2567EBRNZ is a 3 kV rms isolated RS-485 transceiver manufactured by Analog Devices. It integrates an isolated dc-to-dc converter for signal and power isolation. The device supports data rates up to 100 Mbps and operates with supply voltages between 3 V and 5.5 V. It features ±15 kV IEC ESD protection on the bus pins and operates within a temperature range of -40°C to +105°C. The component is housed in a 28-pin SOIC package.

Feature Summary

• Integrates an isolated dc-to-dc converter to provide both signal and power isolation without external magnetic components.
• Provides high electromagnetic compatibility performance, passing EN 55032 Class B emissions testing with margin.
• Offers robust electrostatic discharge protection rated at ±15 kV according to IEC standards.

Applications

• Industrial automation systems requiring galvanic isolation
• Building automation networks utilizing RS-485 communication
• Factory floor control units needing high-speed data transmission

Procurement Notes

Verify the specific suffix (e.g., RL7 for reel) against the required packaging format. Confirm that the 28-pin SOIC footprint matches the design layout. Ensure the voltage requirements align with the 3 V to 5.5 V operating range before finalizing procurement.

Selection Notes

Select this component when high-speed RS-485 communication is required alongside integrated power isolation. It is suitable for designs where board space is limited due to the elimination of external isolation transformers. Consider the thermal performance of the SOIC package under maximum load conditions.

Part Context

This part belongs to the ADM256xE family of isolated RS-485 transceivers from Analog Devices. It shares architectural similarities with models like the ADM2563E but offers higher data rate capabilities. The family is designed for industrial applications demanding reliable long-distance communication.

Replacement Considerations

The ADM2563EBRNZ is a related model within the same family but operates at lower data rates. Verify interface compatibility and speed requirements before substituting. Other members of the ADM256xE series may serve as alternatives if pinouts and isolation ratings match.
