Note:

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.
