TDA7294S

4/16

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 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
