Typical Applications
ADM2582EBRWZ-RL7 is suitable for 6 applications: Industrial Fieldbus Networks, Building Automation, Motor Control Systems, Instrumentation, Power Utility Monitoring, Transportation Systems.
Industrial Fieldbus Networks
The ADM2582EBRWZ-RL7 is ideal for industrial fieldbus networks like PROFIBUS and Modbus, where high data rates up to 16Mbps and robust isolation are required. Its integrated isoPower eliminates the need for external DC-DC converters, simplifying design and reducing board space. The ±15kV ESD protection ensures reliability in harsh industrial environments with frequent transient voltages.
Recommended
Building Automation
In building automation systems, the ADM2582EBRWZ-RL7 provides reliable RS-485 communication for HVAC controllers, lighting systems, and access control panels. Its 2500Vrms isolation protects against ground potential differences between floors and buildings. The wide operating temperature range of -40°C to +85°C ensures operation in unconditioned spaces.
Recommended
Motor Control Systems
The ADM2582EBRWZ-RL7 is used in motor control systems to communicate between the controller and drives over long distances. Its high CMTI of 25kV/µs rejects common-mode transients from motor switching, preventing data corruption. The integrated isolation eliminates ground loops, improving system reliability.
Recommended
Instrumentation
For precision instrumentation, the ADM2582EBRWZ-RL7 provides isolated RS-485 communication between sensors and data acquisition systems. Its low-jitter data transmission and high isolation ensure accurate data transfer in noisy environments. The integrated power supply reduces external component count, simplifying PCB layout.
Recommended
Power Utility Monitoring
In power utility monitoring, the ADM2582EBRWZ-RL7 enables safe communication between high-voltage equipment and control rooms. The 2500Vrms isolation protects operators and low-voltage electronics from dangerous transients. Its high data rate supports real-time monitoring of grid parameters.
Recommended
Transportation Systems
The ADM2582EBRWZ-RL7 is suitable for transportation systems such as railway signaling and traffic control, where reliable communication over long distances is critical. Its robust ESD protection and wide temperature range ensure operation in outdoor environments. The integrated isolation prevents ground loops between different subsystems.

Key Differentiators
- Integrated isoPower eliminates external DC-DC converter (vs ISO3082DW)
- Higher data rate than ADM2483BRWZ (vs ADM2483BRWZ)
- Same package and pinout as ADM2587E (vs ADM2587EBRWZ-REEL7)
Design Notes
Ensure proper creepage and clearance distances for the isolation barrier. The ADM2582E requires at least 8mm creepage for 2500Vrms isolation. Place the isolation barrier in a straight line and avoid routing traces across it.
Decouple the VCC and VISO pins with 0.1µF and 10µF capacitors close to the pins. The integrated isoPower converter can generate switching noise; use a ferrite bead on the VCC input if needed.
Keep the bus lines (A and B) as short as possible and use twisted-pair cabling. Terminate the bus with appropriate resistors (typically 120Ω) to match the characteristic impedance and reduce reflections.
