Notes:

1. Stress greater than 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 above

those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum

rating conditions for extended periods may affect reliability.

Silence Compression

If a particular sound sequence includes periods of silence,

the API840N will automatically compress the silence to

save memory space. This compression will not affect

playback of the sound sequence.
