Electrical specifications

3.1

Absolute maximum ratings

Warning:

Stresses beyond those listed in Table 2 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 AMR conditions for extended periods may affect

device reliability. In the real application, power supplies with

nominal values rated within 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.
