♠ LM4991 3W Audio Power Amplifier e nang le Mokhoa oa ho Shutdown
LM4991 ke mono bridged audio power amplifier e khonang ho fana ka 3W ea matla a tloaelehileng a tsoelang pele ho mojaro oa 3Ω ka tlase ho 10% THD ha e tsamaisoa ke motlakase oa 5V (sheba Tlhokomeliso e ka tlase). Ho baballa matla lits'ebetsong tse nkehang habonolo, LM4991's micropower shutdown mode (ISD = 0.1µA,typ) ea kengoa tšebetsong ha VDD e sebelisoa ho phini ea SHUTDOWN.
Li-amplifiers tsa matla a molumo oa Boomer li etselitsoe ka ho khetheha ho fana ka matla a phahameng, molumo o phahameng oa ho tšepahala. Li hloka likarolo tse seng kae tsa ka ntle 'me li sebetsa ka matla a fokolang a phepelo ho tloha 2.2V ho ea ho 5.5V.Kaha LM4991 ha e hloke tlhahiso ea ho kopanya li-capacitor, li-bootstrap capacitor, kapa marang-rang a li-snubber, e loketse ka mokhoa o nepahetseng bakeng sa lisebelisoa tse nkehang tsa matla a tlaase tse hlokang bonyane ba molumo le boima ba 'mele.
Likarolo tse ling tsa LM4991 li kenyelletsa ts'ireletso ea ho koala ha mocheso, botsitso ba ho fumana bonngoe, le sete ea phaello ea kantle.
