♠ LM4991 3W Isandisi saMandla somsindo esineMowudi yokuCima
I-LM4991 yi-mono bridged audio iamplifier yamandla odiyo ekwaziyo ukuhambisa i-3W yamandla aphakathi aqhubekayo kumthwalo we-3Ω ongaphantsi kwe-10% THD xa inikwe amandla ombane we-5V (bona Qaphela ngezantsi).Ukugcina amandla kwizicelo eziphathwayo, imowudi yokuvala amandla amancinci ye-LM4991 (ISD = 0.1µA,typ) iyasebenza xa i-VDD ifakwa kwi-SHUTDOWN pin.
Izandisi zamandla zomsindo we-Boomer ziyilelwe ngokukodwa ukunika amandla aphezulu, ukuthembeka okuphezulu kwemveliso yomsindo.Bafuna amacandelo ambalwa angaphandle kwaye basebenze kwi-voltages ephantsi yokubonelela ukusuka kwi-2.2V ukuya kwi-5.5V. Ekubeni i-LM4991 ayifuni i-coupling capacitors ephumayo, i-bootstrap capacitors, okanye i-network snubber, ifaneleke ngokufanelekileyo kwiinkqubo eziphathwayo eziphantsi kwamandla ezifuna umthamo omncinci kunye ubunzima.
Iimpawu ezongezelelweyo ze-LM4991 ziquka ukukhuselwa kwe-thermal shutdown, ubunye-inzuzo yokuzinza, kunye neseti yenzuzo yangaphandle.
