Note (*):

MUSIC POWER CONCEPT

MUSIC POWER is the maximal power which the amplifier is capable of producing across the rated load resistance (regardless of non linearity)

1 sec after the application of a sinusoidal input signal of frequency 1KHz.

Note (**): Tested with optimized Application Board (see fig. 2)

Note (***): Limited by the max. allowable current.
