Analog Devices ADM2582EBRWZ Datasheet
The ADM2582EBRWZ is a high-speed, 16 Mbps isolated transceiver designed for balanced multipoint transmission lines. By utilizing Analog Devices’ proprietary iCoupler® digital isolation and isoPower DC-to-DC converter technologies, it eliminates the need for an external isolated power supply, significantly reducing PCB footprint, design complexity, and overall bill-of-materials (BOM) costs.
The ADM2582EBRWZ is currently In Stock and ready for immediate shipping at ICHOME. As a leading independent distributor, we ensure 100% authenticity, comprehensive quality control testing, and rapid global delivery to keep your production lines moving without interruption.

Supply Chain & Procurement Insights
Navigating the semiconductor lifecycle requires proactive planning, particularly for specialized analog and interface ICs.
Manufacturer: Analog Devices (ADI) is the market leader in galvanic isolation technologies. Parts carrying their hallmark guarantee premium longevity and strict compliance with global safety infrastructure.
Lead Time Trend: The industrial communication sector continues to experience steady demand. While factory lead times from original component manufacturers (OCMs) for the ADM258x family can occasionally fluctuate between 16 to 26 weeks during supply chain pinches, ICHOME maintains a buffered pipeline and immediate safety stock of ADM2582EBRWZ to help buyers bypass factory lead-time.
Drop-In Replacements & Functional Alternatives of ADI ADM2582EBRWZ
When facing strict project timelines or temporary allocation shortages, procurement managers can evaluate these recommended alternatives:
ADM2587EBRWZ (Functional Equivalent): Also manufactured by Analog Devices, the ADM2587E shares the exact same pin configuration, package (20-lead SOIC_W), and internal isoPower architecture. The primary distinction is the data rate: the ADM2587E is optimized for lower-speed, long-distance transmission up to 500 kbps, featuring slew-rate limited drivers to minimize Electromagnetic Interference (EMI). If your network operates below 500 kbps, it serves as a reliable replacement.
ADM2867EBRWZ (Next-Generation Upgrade): For newer designs, this part offers enhanced 5700V rms isolation and lower emissions, though it requires an evaluation of slight register/pin configuration nuances depending on the exact hardware layout revision.
Core Application of ADM2582EBRWZ
The component is rigorously deployed across major industrial and commercial systems throughout the North American and European markets:
Industrial Field Networks: Profibus, Modbus, and generic RS-485 fieldbus architectures.
Energy Management: Solar inverters, wind turbine control panels, and battery management systems (BMS).
Building Automation: High-node HVAC control grids, security elevators, and infrastructure monitoring.
Multipoint Data Transmission: Long-haul telemetry systems prone to massive ground loops.
What Is the Difference Between the ADM2582E and the ADM2587E?
The core difference between the ADM2582E and ADM2587E lies in their maximum data rate and driver characteristics. The ADM2582E supports high-speed data transmission up to 16 Mbps, making it ideal for high-throughput industrial interfaces. Conversely, the ADM2587E is restricted to a maximum data rate of 500 kbps but utilizes slew-rate-limited drivers. These limited drivers reduce reflections and electromagnetic emissions (EMI), making the ADM2587E more forgiving in complex, poorly terminated, or longer-distance cabling environments. Both devices share identical packages, pinning layouts, and voltage options.
