Key Differentiators
- Integrated power isolation with 200 mA output (vs ISO3082)
- Higher data rate (16 Mbps) (vs ADM2687EBRIZ)
- 5 kV isolation with 25 kV/µs CMTI (vs ISO3082)
Design Notes
For 5 kV isolation, ensure adequate creepage and clearance distances on the PCB. The SOIC-16 wide body package provides 8 mm creepage, but maintain at least 8 mm spacing between the logic and bus side copper areas. Use a ground plane split under the device to prevent common-mode noise coupling.
The integrated DC-DC converter draws significant current during startup. Place a 10 µF tantalum capacitor on VDD2 and a 0.1 µF ceramic capacitor close to the VDD1 and VDD2 pins. Ensure the input supply can provide at least 200 mA to the isolated side.
The ADM2682EBRIZ dissipates power internally due to the DC-DC converter. At 16 Mbps and full load, the device may warm up. Ensure adequate airflow or a thermal pad on the PCB. The SOIC-16 package has a theta_JA of approximately 80°C/W; keep ambient temperature below 85°C to avoid thermal shutdown.
Compliance Information
