Electrical specifications

3.1

Absolute maximum ratings

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.
