Stresses beyond those listed in
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 under
“Recommended operating conditions” are not implied.
Exposure to absolute-maximum-rated conditions for
extended periods may affect device reliability. In the real
application, power supplies with nominal values rated within
the recommended operating conditions may rise beyond the
maximum operating conditions for a short time when no or
very low current is sunk (amplifier in mute state). In this case
the reliability of the device is guaranteed, provided that the
absolute maximum ratings are not exceeded.
