ADM2483BRWZ

Overview

The ADM2483BRWZ is a three-channel digital isolator combined with an RS-485 transceiver, utilizing iCoupler magnetic coupling technology. It integrates a three-state differential line driver and a differential input receiver within a single 16-pin SOIC package. The device supports data rates up to 500 kbps and operates on supply voltages ranging from 2.7 V to 5.5 V. It provides 2500 Vrms electrical isolation and features high common-mode transient immunity exceeding 25 kV/µs. Key protections include thermal shutdown and glitch-free power-up/down behavior.

Feature Summary

• Integrates three independent digital isolators with an RS-485 transceiver using iCoupler magnetic coupling technology
• Provides 2500 Vrms electrical isolation capability certified under UL 1577 standards
• Features high common-mode transient immunity exceeding 25 kV/µs for robust noise rejection
• Includes thermal shutdown protection and glitch-free power-up/down logic states

Applications

• Isolated industrial communication interfaces
• Building automation control networks
• Process control systems requiring galvanic isolation

Procurement Notes

Verify the specific suffix BRWZ confirms the wide-body SOIC-16 package and commercial temperature range. Confirm RoHS compliance status as required by your assembly specifications. Ensure the ordering quantity matches the tube packaging format typically associated with this part number variant. Cross-reference the manufacturer's latest datasheet revision to confirm pinout consistency before finalizing procurement.

Selection Notes

Select this component when designing systems requiring isolated RS-485 or RS-422 communication channels. It is suitable for applications needing multiple isolated signal paths within a single footprint. Consider its 500 kbps data rate limit against higher-speed requirements. Evaluate the 2500 Vrms isolation barrier against system safety certification needs. The integrated driver and receiver simplify board layout compared to discrete solutions.

Part Context

This device belongs to Analog Devices' family of iCoupler-based interface products. It combines digital isolation with standard bus transceiver functionality. The series targets industrial environments where ground potential differences and noise interference are prevalent. It replaces traditional transformer or optocoupler-based designs with a more compact integrated solution.

Replacement Considerations

Check for ADM2483 variants with different suffixes indicating package or temperature changes. Verify functional compatibility with ADM2482 if only two channels are needed. Ensure substitute parts maintain the same 16-pin SOIC footprint and isolation voltage ratings.
