Design Notes
For 5 kV isolation, ensure PCB creepage and clearance distances meet safety standards. The SOIC-16 package has a minimum creepage of 8 mm, but you must maintain at least 8 mm spacing between the high-voltage and low-voltage sides on the PCB. Use a slot or cutout under the isolator to increase creepage distance if needed.
Decouple both VDD1 and VDD2 with 0.1 µF ceramic capacitors placed as close to the pins as possible. Additionally, use a 10 µF bulk capacitor on each side if the supply is shared with other components. The ADuM2250 draws quiescent current of approximately 5 mA per side, so ensure the supply can handle the load.
Keep the I2C traces short and avoid routing them near high-voltage or high-current traces to minimize noise coupling. Use ground planes on both sides of the isolation barrier, but do not connect them together. The iCoupler technology is sensitive to magnetic fields, so avoid placing the device near transformers or inductors.
Compliance Information
RoHS compliant per Analog Devices product page. AEC-Q100 not applicable for standard version; automotive version ADUM2250WARWZ is AEC-Q100 qualified.
