Electrical specifications
3.1
Absolute maximum ratings
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, the power supply with the nominal value rated in
the recommended operating conditions, may rise beyond the
maximum operating condition 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 rating is not exceeded.
