Input capacitance is from any input data pin to ground.

REGULATORY INFORMATION

The ADuM7640/ADuM7641/ADuM7642/ADuM7643 are approved by the organizations listed in Table 14. See Table 18 and the

Insulation Lifetime section for recommended maximum working voltages for specific cross-isolation waveforms and insulation levels.

In accordance with UL 1577, each ADuM7640/ADuM7641/ADuM7642/ADuM7643 is proof tested by applying an insulation test voltage ≥ 1200 V rms for 1 sec (current

leakage detection limit = 5 µA).
