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 IS22C040 will automatically compress the silence to
save memory space. This compression will not affect
playback of the sound sequence.
