DC Voltage 2 VDD1 is the power supply for the push-pull transformer, and VDDA is the power supply of Side 1 of the ADuM3070. Basic Insulation 848 V peak Working voltage 3 Refers to common-mode transients across the insulation barrier. Common- per IEC 60950-1 mode transients exceeding the absolute maximum ratings may cause latch-up or permanent damage. 1 Refers to the continuous voltage magnitude imposed across the isolation barrier. See the Insulation Lifetime section for more information. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any
ESD CAUTION
other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Rev.
