MUSIC POWER CONCEPT
MUSIC POWER is the maximal power which the amplifier is capable of producing across the rated load resistance (regardless of non lin-
earity) 1 sec after the application of a sinusoidal input signal of frequency 1KHz.
Note (**): Tested with optimized Application Board (see fig. 3)
Note (***): Limited by the max. allowable current.
Note (***): For supply voltage ≥35V, The device could be demaged in short circuit conditions when the input signal is applied
