Absolute Maximum Ratings are stress ratings. Stresses in
excess of these ratings can cause permanent damage to
the device. Functional operation of the device at these or
any other conditions beyond those indicated in the opera-
tional sections of this data sheet is not implied. Exposure of
the device to the absolute maximum ratings for an extend-
ed period may degrade the device and effect its reliability.

1. All DC voltages are referenced to V
SS.
2. Vrms per tone, 540 W load.
3. Any one frequency relative to the lowest level output tone (f<4000 Hz).
4. 0 dBm = 0.775 Vrms.
5. To 90% maximum amplitude.
6. For all supply voltages in the operating range.
