 In accordance with UL 1577, each ADuM1440/ADuM1441/ADuM1442/ADuM1445/ADuM1446/ADuM1447 is proof tested by applying an insulation test voltage and 
measuring leakage during final production testing. QSOP package devices are tested at ≥3000 V rms for 1 sec with a current leakage detection limit = 5 μA. SSOP 
package devices are tested at ≥4500 V rms for 1 sec with a current leakage detection limit = 10 μA.
