Warning:
Stresses beyond those listed under “Absolute maximum
ratings” make 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
under “Recommended operating condition” are not implied.
Exposure to absolute-maximum-rated conditions for
extended periods may affect device reliability. In the real
application, power supply with nominal value rated inside
recommended operating conditions, may experience some
rising beyond the maximum operating condition for short
time when no or very low current is sinked (amplifier in mute
state). In this case the reliability of the device is guaranteed,
provided that the absolute maximum rating is not exceeded.
