ADM2483BRW-REEL

Overview

The ADM2483BRW-REEL is a half-duplex RS-485 transceiver utilizing iCoupler magnetic coupling technology for galvanic isolation. It integrates a three-channel isolator, a three-state differential line driver, and a differential input receiver within a 16-pin SOIC package. The device supports data rates up to 500 kbps with a supply voltage range of 2.7 V to 5.5 V. It provides 2500 Vrms isolation strength certified under UL 1577 standards and offers high common-mode transient immunity exceeding 25 kV/µs. Operating temperatures span from -40°C to +85°C.

Feature Summary

• Integrates three-channel digital isolation using iCoupler magnetic coupling technology
• Provides robust protection against common-mode transients exceeding 25 kV/µs
• Includes fail-safe receiver design to ensure logic high output when inputs are open
• Features thermal shutdown protection to prevent damage during overheating events

Applications

• Industrial automation control systems requiring isolated RS-485 communication
• Building automation networks utilizing balanced multipoint bus architectures
• Isolated interface circuits in instrumentation and measurement equipment
• Power metering applications needing galvanic separation between logic and bus sides

Procurement Notes

Verify the specific suffix indicates reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation. Ensure the component matches the active lifecycle status. Validate that the 16-pin SOIC footprint aligns with PCB layout requirements. Check for any specific handling precautions related to electrostatic discharge sensitivity.

Selection Notes

Select this component for designs requiring integrated isolation without external transformer components. It is suitable for applications demanding high common-mode noise rejection in electrically noisy environments. Consider the 500 kbps speed limit when evaluating higher throughput requirements. Verify power supply constraints match the 2.7 V to 5.5 V operating range. Assess thermal management needs based on the specified junction temperature limits.

Part Context

This part belongs to the ADM2483 family of isolated RS-485 transceivers manufactured by Analog Devices. The series leverages proprietary iCoupler technology to replace traditional magnetic isolation methods. These devices are designed to simplify board layout while maintaining safety certification requirements. The family targets industrial and commercial applications needing reliable long-distance serial communication.

Replacement Considerations

ADM2483BRWZ is a compatible variant available in tube packaging instead of reel format. Both parts share identical electrical specifications and pinouts. Verify packaging differences impact assembly line processes before substitution.
