Warning:
Stresses beyond those listed in Table 3 above 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 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 experience
some rising beyond the maximum operating conditions for a
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 ratings are
not exceeded.
