Product Overview
ADM2587EBRWZ is the base order code for the 500 kbps ADM2587E isolated RS-485/RS-422 transceiver. Its electrical architecture integrates the digital isolation barrier, differential bus interface, and isolated dc-to-dc power conversion.
The non-reel order code does not change the verified electrical limits, but it remains a distinct procurement identifier. BOMs, RFQs, and incoming inspection should preserve ADM2587EBRWZ rather than silently rewriting it to a reel-suffixed code.

Key Features
- 500 kbps isolated RS-485/RS-422 physical layer.
- Integrated isoPower isolated dc-to-dc converter.
- ±15 kV bus-pin ESD protection and >25 kV/µs CMTI.
- Up to 256-node bus loading.
Functional Highlights
The 500 kbps timing grade is the major electrical distinction from the 16 Mbps ADM2582E family member.
Procurement packaging suffixes do not change the core device function, but exact order-code control is still necessary for sourcing and traceability.
Application Fit
- Isolated RS-485/RS-422 interfaces.
- Industrial field networks.
- Multipoint data transmission systems.
Design Considerations
- Check 500 kbps against cable and system timing requirements.
- Follow isoPower emissions-control and decoupling guidance.
- Apply suitable bus termination and biasing.
- Preserve ADM2587EBRWZ as the exact BOM identity.
