1 In accordance with UL 1577, each ADuM3480/ADuM3481/ADuM3482 is proof tested by applying an insulation test voltage of ≥4500 V rms for 1 second (current
leakage detection limit = 10 µA).
2 In accordance with DIN V VDE V 0884-10, each of the ADuM348x is proof tested by applying an insulation test voltage of ≥1050 V peak for 1 second (partial discharge
detection limit = 5 pC). The asterisk (*) marking branded on the component designates DIN V VDE V 0884-10 approval.
