¹The device is considered a 2-terminal device: Pin 1 through Pin 8 are shorted together, and Pin 9 through Pin 16 are shorted together.

REGULATORY INFORMATION

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

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

Table 3.

Recognized under the 1577 component recognition program¹

Single/basic insulation, 2500 V rms isolation voltage

¹In 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).
