Quad-Channel Isolators with Integrated DC-to-DC Converter

Analog Devices 

ADuM5401/ADuM5402/ADuM5403/ADuM5404

DIN V VDE V 0884-10 (VDE V 0884-10) INSULATION CHARACTERISTICS

These isolators are suitable for reinforced electrical isolation only within the safety limit data. Maintenance of the safety data is ensured by

protective circuits. The asterisk (*) marking on packages denotes DIN V VDE V 0884-10 approval.
