1 In accordance with UL 1577, each ADuM2250/ADuM2251 is proof tested by applying an insulation test voltage ≥ 6000 V rms for 1 sec (current leakage detection limit = 10 μA).

2 In accordance with DIN V VDE V 0884-10 (VDE V 0884-10):2006-12, each ADuM2250/ADuM2251 is proof tested by applying an insulation test voltage ≥ 1590 V peak for 1 sec

(partial discharge detection limit = 5 pC). The asterisk (*) marking branded on the component designates DIN V VDE V 0884-10 (VDE V 0884-10):2006-12 approval.
