1 In accordance with UL 1577, each ADuM7703 is proof tested by applying an insulation test voltage ≥ 6840 V rms for 1 sec (current leakage detection limit = 15 μA).

2 In accordance with DIN V VDE V 0884-10, each ADuM7703 is proof tested by applying an insulation test voltage ≥ 2344 VPEAK for 1 sec (partial discharge detection limit = 5 pC).

3 Rating is calculated for a pollution degree of 2 and a Material Group III. The ADuM7703 package material is rated by CSA to a CTI of >600 V and, therefore, Material Group I.
