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

These ADuM220N/ADuM221N/ADuM225N/ADuM226N isolators are suitable for reinforced electrical isolation only within the safety

limit data. Protective circuits ensure the maintenance of the safety data. The * marking on packages denotes DIN V VDE V 0884-10

approval.
