Conectare intrare amplificator


Recommended Posts

Salut,am un cititor de stick care are incorporat un mic amplificator de 1 watt(LM4995),si vreau sa-l leg la un amplificator cu TDA,cum leg intrarea in TDA stiind ca LM are iesirea in punte?Am atasat o schema in Eagle,daca leg OUT2 la GNDintrare ar fi ca si cum as pune iesirea unul final din LM la masa.

Exact. Chiar dacă ieşirea e în punte, semnalele sînt în contratimp faţă de masă, deci poţi lua semnalul de la oricare din ele. E posibil ca pentru una din ele să nu fie nevoie de sarcină, dar nu bag mîna în foc.
