How do they come up with ratings on some of these chips? I was looking at the specs for TDA7376B:
2 x 25W/4ohm @ 14.4V, 1khz, 10%
but when I look at the graph for THD vs. Ouput power it seems it hits 10% THD before reaching 12 watts.
Can someone explain?
The 1kHz curve is the lower of the two. 10 % THD is the upper limit of the graph. It looks like the 1kHz curve hits the 10 % line at more or less 25 W.
Thanks guys. Definitely read the graph wrong. Obviously should have just went to bed last night and looked again in the morning. I'm usually not quite that dense. 😱
