Stress beyond above listed “Absolute Maximum Ratings” may lead permanent damage to the device. These are stress ratings only and
operations of the device at these or any other conditions beyond those indicated in the operational sections of the specifications are not
implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
NOTE 1: Based on long term current density limitations.
NOTE 2: The A7801 are guaranteed to meet performance specifications from 0℃ to 70℃ Specifications over the –40℃ to 85 operating
temperature range are assured by design, characterization and correlation with statistical process controls.
