TDA7296
Table 4. Electrical Characteristcs (Refer to the Test Circuit VS = ±24V, RL = 8
Ω, GV = 30dB; Rg = 50Ω;
Tamb = 25°C, f = 1 kHz; unless otherwise specified).
Note (*):
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.5)
