3.1

Absolute maximum ratings

Warning:

Stresses beyond those listed in Table 3: Absolute maximum

ratings 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 in

Table 5: Recommended operating conditions are not implied.

Exposure to absolute maximum rated conditions for

extended periods may affect device reliability. In the real

application, a power supply with nominal value rated within

the limits of 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.
