REGULATORY INFORMATION

The ADuM1234 has been approved by the organization listed in Table 3. Refer to Table 7 and the Insulation Lifetime section for details

regarding recommended maximum working voltages for specific cross-isolation waveforms and insulation levels.

Table 3.

UL

Recognized under the 1577 component recognition program1

Single/basic insulation, 2500 V rms isolation voltage

1 In accordance with UL1577, each ADuM1234 is proof tested by applying an insulation test voltage ≥ 3000 V rms for 1 second (current leakage detection limit = 5 μA).
