TDA7370B OUTPUT STAGE The fully complementary output stage was made possible by the development of a new compo- nent: the ST exclusive power ICV PNP. A novel design based upon the connection shown in fig. 19 has then allowed the ...

Offset Control The quiescent output voltage must be as close as possible to its nominal value, so that less undis- torted power would be available. For this reason an input bias current compensa- tion is implemented to reduce the voltage ...

TDA7370B Polarity Inversion High current (up to 10A) can be handled by the device with no damage for a longer period than the blow-out time of a quick 2A fuse (normally connected in series with the supply). This fea- tures ...
