What are the key features of the ADM2587EBRWZ-REEL7?
The ADM2587EBRWZ-REEL7 is a highly integrated isolated RS-485/RS-422 transceiver that includes both digital isolation and an integrated isoPower® isolated DC-to-DC converter. It supports data rates up to 500 kbps, offers ±15 kV ESD protection on bus pins, and provides 2500 Vrms isolation with a high common-mode transient immunity (CMTI) of over 25 kV/µs. It includes fail-safe receiver inputs, thermal shutdown protection, and complies with industry communication standards such as ANSI/TIA/EIA-485-A-98 and ISO 8482:1987(E). The device operates from either 3.3 V or 5 V, supports up to 256 nodes, and comes in a 20-lead wide-body SOIC package.
What is the ADM2587EBRWZ-REEL7 used for?
This device is used in systems requiring reliable, noise-immune, and isolated communication over RS-485/RS-422 networks. It is commonly found in industrial automation equipment, motor control systems, power-monitoring systems, building automation, HVAC controllers, programmable logic controllers (PLCs), and distributed sensor networks. The integrated isolation and DC-DC converter allow designers to simplify board layout and reduce component count in applications where electrical isolation is essential for safety and signal integrity.
Does it support full-duplex or half-duplex communication?
Yes. The ADM2587EBRWZ-REEL7 can be configured for either half-duplex or full-duplex, making it flexible for various RS-485/RS-422 network structures.
What makes its isolation capabilities important?
The 2500 Vrms insulation barrier protects low-voltage circuitry from high-voltage spikes, ground-potential differences, and electrical noise. This is especially important in industrial environments where equipment may operate across different power domains or long cable distances.
What advantages does the integrated isoPower® DC-to-DC converter provide?
It eliminates the need for an external isolated power supply, reducing board space, cost, and design complexity. This helps engineers implement isolated communication interfaces more quickly and cleanly.
