The high CMTI ensures reliable data transmission in the presence of electrosurgical interference, and the wide temperature range supports sterilization processes.
Recommended
Solar Inverters
In solar power systems, the ADM2484EBRWZ-RL7 isolates the communication between the inverter and monitoring systems. Its 5000 Vrms isolation handles high common-mode voltages from the PV array, while the 500 kbps data rate supports real-time monitoring. The device's wide temperature range and high CMTI ensure reliable operation in outdoor environments with rapid voltage transients.
Recommended
Transportation Systems
The ADM2484EBRWZ-RL7 is used in railway and automotive communication networks, where isolation is critical for safety. Its 5000 Vrms isolation protects against high-voltage surges, and the ±15 kV ESD protection withstands harsh electromagnetic environments. The device's wide temperature range and high CMTI make it suitable for traction control and signaling systems.

Key Differentiators
- Higher isolation voltage (5000 Vrms) compared to ADM2483BRWZ-RL7 (vs ADM2483BRWZ-RL7)
- Higher data rate (500 kbps) compared to ISO3082DW (vs ISO3082DW)
- Wider operating temperature range (-40°C to +125°C) compared to ISO3082DW (vs ISO3082DW)
Design Notes
Decouple VDD1 and VDD2 with 0.1 µF ceramic capacitors placed as close as possible to the pins. For noisy industrial environments, add a 10 µF electrolytic capacitor in parallel. Ensure VDD2 is within 3.0V to 3.6V; exceeding this range can damage the bus side.
Maintain a clearance of at least 8 mm between the logic side (VDD1/GND1) and bus side (VDD2/GND2) traces to preserve the 5000 Vrms isolation rating. Avoid routing high-voltage traces under the IC. Use a solid ground plane on each side, but do not connect GND1 and GND2 together.
For half-duplex operation, tie Y to A and Z to B externally. Do not forget to enable the driver (DE high) and receiver (RE low) appropriately. Terminate the bus with 120 Ω at both ends to prevent reflections. Also, consider adding a common-mode choke for enhanced EMI immunity.
