Daca tot exista o categorie despre amplificatoare, de ce n-o folosesti !? Pe viitor mai multa atentie te rog! Multumesc! Link to comment Share on other sites More sharing options...

margarit2001 Posted April 14, 2006 Share Posted April 14, 2006 din datasheetul tda8560q: " SHORT-CIRCUIT PROTECTIONWhen a short-circuit occurs at one or more outputs toground or to the supply voltage, the output stages areswitched off until the short-circuit is removed and thedevice is switched on again, with a delay of approximately20 ms, after removal of the short-circuit. ................The power dissipation in any short-circuit condition isvery low.......... approximately 40 mA. "morala - nu ai nimic in scurtdaca se incinge repede e "dus" , schimba-lam avut de-a face cu acest IC si cand era ars asa facea- se incingea de moarte :smt003 Link to comment Share on other sites More sharing options...
niq_ro Posted April 15, 2006 Share Posted April 15, 2006 e bine sa studiezi si datasheet-ul acestui integrat, cel de la http://www.semiconductors.philips.com/pip/TDA8560.html sau vezi documentatia kitului de la http://www.adelaida.ro/pub/Docs/AD_005.1.pdf foarte posibil e sa fie radiatorul subdimensionat asa ca-i poti pune unul mai mare si/sau un ventilator (cooler) de sursa de calculator banuiesc ca-l alimentezi la +12V ....si ca ai pus radiator :partyman: Link to comment Share on other sites More sharing options...
