DIN V VDE V 0884-10 (VDE V 0884-10): 2006-12 INSULATION CHARACTERISTICS
The ADuM1310/ADuM1311 isolators are suitable for reinforced electrical isolation within the safety limit data only. Maintenance of the
safety data is ensured by protective circuits. The asterisk (*) marked on packages denotes DIN V VDE V 0884-10 approval for 560 V peak
working voltage.
