Capacitance (Input to Output)
1 The device is considered a 2-terminal device. For the 16-lead SOIC_W, Pin 1 to Pin 8 are shorted together and Pin 9 to Pin 16 are shorted together. For the 8-lead
SOIC_IC, Pin 1 to Pin 4 are shorted together and Pin 5 to Pin 8 are shorted together.

1 In accordance with UL 1577, each ADuM7704 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 ADuM7704 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 ADuM7704 package material is rated by CSA to a comparative tracking index (CTI) of >600 V
and, therefore, Material Group I.
