Layout Considerations

Normally, a snubber is not needed at the output of the IC, unlike many other audio amplifiers.

However, the PC-board layout, stray capacitances, and the manner in which the speaker wires

are configured may dictate otherwise. Generally, the speaker wires should be twisted tightly,

and should not be more than a few cm (or inches) in length.

Absolute Maximum Ratings

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating

only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this

specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
