ROHM BD7280YG-C Voltage Su'e le pisapisao maualalo ma le fa'aulufaleina o alavai-to-rail High Speed CMOS Fa'agaioiga Amplifier mo Ta'iala mo Tagata Ta'avale
E fa'atusaina e lenei matagaluega le tali fa'atele i le Op-Amp e pei o se voltage mulimuli. E mafai ona e matauina le maua o le AC ma le vaega o le fua faatatau o galuega faatino i vol voltagu pe a maua le puna voltage suia le alaleo AC. E mafai ona e faʻavasegaina faʻasologa o vaega o loʻo faʻaalia i le lanumoana, e pei o le VSOURCE, poʻo vaega pito i luga, ma faʻatusa le voltage mulimuli ma le tulaga e mana'omia. E mafai ona e fa'ata'ita'ia le ta'amilosaga i le tusi talosaga fa'asalalau: Fa'agaioiga amplifier, Fa'atusatusa (Tutorial). [JP] [EN] [CN] [KR]
Lapataiga Lautele
Lapataiga 1: E le fa'amaonia le tau mai i'uga fa'atusa. Fa'amolemole fa'aaoga tali nei e fai ma ta'iala mo lau mamanu.
Lapataiga 2: O uiga fa'ata'ita'i nei e fa'apitoa ile Ta=25°C. O le mea lea, o le faʻataʻitaʻiga iʻuga ma fesuiaiga o le vevela atonu e matua ese lava mai le taunuuga ma le mea na faia i le laupapa talosaga moni (fuaina moni).
Lapataiga 3: Fa'amolemole tagai i le tusi talosaga a le Op-Amps mo fa'amatalaga o fa'amatalaga fa'apitoa.
Lapataiga 4: O uiga e mafai ona suia e faʻatatau i le mamanu moni o le laupapa ma e fautuaina malosi e le ROHM e faʻalua le siakiina o na uiga ma le laupapa moni o le a faʻapipiʻi ai meataalo.

Fa'afefea ona fa'atusa
O fa'asologa fa'ata'ita'iga, e pei o le salu fa'amaufa'ailoga po'o le fa'aliliuga o filifiliga, e mafai ona fa'atulagaina mai le 'Simulation Settings' o lo'o fa'aalia i le Ata 2, ma le Laulau 1 o lo'o fa'aalia ai le fa'aogaina o le fa'ata'ita'iga. I le tulaga o le simulation convergence mataupu, e mafai ona e suia filifiliga alualu i luma e foia. O le vevela e seti i le 27 °C i le faʻamatalaga faʻaletonu i le 'Filifiliga Tusia'. E mafai ona e suia.
