1 In accordance with UL 1577, each ADuM1440/ADuM1441/ADuM1442/ADuM1445/ADuM1446/ADuM1447 is proof tested by applying an insulation test voltage of
≥3000 V rms for 1 sec (current leakage detection limit = 5 µA).
2 In accordance with DIN V VDE V 0884-10, each ADuM1440/ADuM1441/ADuM1442/ADuM1445/ADuM1446/ADuM1447 is proof tested by applying an insulation test
voltage ≥1050 VPEAK for 1 second (partial discharge detection limit = 5 pC). The asterisk (*) marked on the component designates DIN V VDE V 0884-10 approval.
