REGULATORY INFORMATION

The ADuM1420 will be approved by the organization listed in Table 3.

Table 3.

UL1 (Pending)

Recognized under 1577 component recognition program, basic insulation, 1667 V rms isolation voltage.

1 In accordance with UL 1577, each ADuM1420 is proof tested by applying an insulation test voltage ≥ 2000 V rms for 1 second (current leakage detection limit = 5 μA).
