ADM2687EBRIZ-RL7

Overview

The ADM2687EBRIZ-RL7 is a 5 kV rms signal and power isolated RS-485 transceiver featuring ±15 kV ESD protection. It integrates an isoPower DC-to-DC converter, eliminating external isolation components. The device supports data rates up to 500 kbps with a supply voltage range of 3.0 V to 5.5 V. It operates within a temperature range of -40°C to +85°C and is housed in a 16-lead SOIC package.

Feature Summary

• Integrates a 5 kV rms isolated DC-to-DC converter for simultaneous signal and power isolation without external magnetics
• Provides robust ±15 kV electrostatic discharge (ESD) protection on all bus pins
• Incorporates current limiting and thermal shutdown to prevent damage from output shorts or excessive power dissipation

Applications

• Isolated RS-485/RS-422 communication interfaces
• Industrial fieldbus networks requiring galvanic isolation
• Multi-point data transmission systems in noisy environments

Procurement Notes

Verify the specific model suffix against official Analog Devices documentation to confirm the 500 kbps data rate variant. Ensure the order matches the required SOIC-16 package and industrial temperature range specifications. Cross-reference the manufacturer part number directly with the datasheet to avoid confusion with similar high-speed variants in the family.

Selection Notes

Select this component when system design requires integrated power isolation to reduce board space and component count. It is suitable for applications needing high ESD immunity on the bus side. Compare performance requirements against higher-speed models if data throughput exceeds 500 kbps. Verify that the 5 kV rms isolation rating meets the safety standards of the target application environment.

Part Context

This part belongs to the ADM268xE series of isolated transceivers from Analog Devices. It utilizes iCoupler technology for digital isolation and isoPower for energy transfer across the isolation barrier. The series is designed to simplify the implementation of isolated serial communication links in industrial and instrumentation applications.

Replacement Considerations

The ADM2682E is a related variant offering higher data rates up to 16 Mbps. Verify if the increased speed is necessary for the application. Both parts share similar isolation features and pinouts but differ in maximum data rate specifications.
