♠ LM4991 3W Audio Power Amplifier fa'atasi ai ma Faiga Tapuni
O le LM4991 o se fa'aola leo fa'apipi'i fa'atasi e mafai ona tu'uina atu le 3W o le malosi fa'aauau pea i totonu o le uta 3Ω ma le itiiti ifo i le 10% THD pe'a fa'aola e se sapalai eletise 5V (silasila i le Fa'amatalaga i lalo). Ina ia fa'asaoina le paoa i mea feavea'i, o le LM4991's micropower shutdown mode (ISD = 0.1µA, typ) e fa'agaoioia pe a fa'aoga VDD i le pine SHUTDOWN.
Boomer power amplifiers ua mamanuina faapitoa e maua ai le malosi maualuga, maualuga leo faʻamaoni. Latou te manaʻomia ni nai vaega i fafo ma faʻaogaina i luga ole eletise maualalo mai le 2.2V i le 5.5V. Talu ai o le LM4991 e le manaʻomia ni masini faʻapipiʻi faʻapipiʻi, capacitors bootstrap, poʻo fesoʻotaʻiga snubber, e fetaui lelei mo masini feaveaʻi maualalo e manaʻomia le laʻititi ma le mamafa.
O mea fa'aopoopo LM4991 e aofia ai le puipuiga o le tapuni vevela, fa'amautu-gain mautu, ma le seti o tupe maua mai fafo.
