Isolation Group
In accordance with UL 1577, each AD7400 is proof tested by applying an insulation test voltage ≥ 6000 V rms for 1 second (current leakage detection limit = 15 μA).
In accordance with DIN V VDE V 0884-10, each AD7400 is proof tested by applying an insulation test voltage ≥ 1671 V peak for 1 second (partial discharge detection
limit = 5 pC).
