LM4991
LM4991 waa cod-weyneeye koronto maqal ah oo isku xiran oo awood u leh in uu keeno 3W ee celceliska tamarta joogtada ah ee culeyska 3Ω oo ka yar 10% THD marka ay ku shaqeyso sahay koronto 5V ah (eeg qoraalka hoose). Si loo xafido awooda codsiyada la qaadi karo, qaabka xidhida awooda-yar ee LM4991 (ISD = 0.1µA, type) waxa la hawlgeliyay marka VDD lagu dabaqo pinka SHUTDOWN.
Cod-weyneyaasha awoodda maqalka ee Boomer waxaa si gaar ah loogu talagalay inay bixiyaan awood sare, wax soo saar maqal oo daacadnimo sare leh. Waxay u baahan yihiin qaybo yar oo dibadda ah waxayna ku shaqeeyaan koronto yar oo sahayda ah laga bilaabo 2.2V ilaa 5.5V.Maadaama LM4991 uma baahna wax soo saarka isku-xireyaasha, capacitors bootstrap, ama shabakadaha snubber, waxay ku habboon tahay nidaamyada la qaadi karo ee hooseeya ee u baahan mugga ugu yar iyo miisaanka.
Tilmaamo dheeraad ah oo LM4991 ah waxaa ka mid ah ilaalinta xiritaanka kulaylka, xasilloonida-helidda midnimada, iyo dejinta faa'iidada dibadda.
• Waxa laga heli karaa Baakadaha Badbaadinta Hawada WSON iyo SOIC
Habka Xiritaanka hadda ee aad u hooseeya
• Waxa uu wadi karaa culaysyo awood leh ilaa 500pF
• Riix oo la hagaajiyay iyo wareegyada pop-gu waxay yareeyaan buuqa inta lagu jiro daminta iyo daminta kala-guurka
• 2.2 - 5.5V Hawlgalka
• Ma jirto Capacitors Coupling, Snubber Networks, Capacitors Bootstrap Capacitors ama Dejinta Faa'iidooyinka Loo Baahan Yahay
• Midnimo- Faa'iido Xasilooni
• Taleefannada gacanta ee wireless-ka iyo gacanta
• PDAs
