AS5055A − Absolute Maximum Ratings
Stresses beyond those listed in Absolute Maximum Ratings” on
page 5 may cause permanent damage to the device. These are
stress ratings only, and functional operation of the device at
these or any other conditions beyond those indicated in
“Electrical Characteristics” on page 6 is not implied. Exposure
to absolute maximum rating conditions for periods may affect
device reliability.
