Filifiliga ma Fa'aoga
Filifiliga ma le faʻaogaina o mea faʻapipiʻi.
E tele vaega ma ituaiga o faʻapipiʻi faʻaogaina faʻamalosi, lea e tatau ona filifilia talafeagai ma faʻaoga e tusa ai ma manaʻoga moni o le faʻaaogaina.
(1) Taumafai e fa'aoga mea fa'apitoa tu'ufa'atasiga fa'apipi'i fa'agaioiga.A fa'aogaina e se faiga le tele o mea fa'aola fa'agaioiga, i le mamao e mafai ai ona fa'aogaina le tele o fa'aupuga fa'apipi'i fa'agaioiga, e pei o le LM324, LF347, ma isi, e fa fa'agaoioiga fa'apipi'i fa'atasi i totonu o se ta'amilosaga tu'ufa'atasi.
(2) O le filifiliga tonu o se faʻapipiʻi faʻapipiʻi faʻapipiʻi, ae ia mafaufau foi i le natura o le faʻailoga (o se punavai voltage poʻo le puna o loʻo i ai nei), o le natura o le uta, faʻapipiʻiina le faʻaogaina o le faʻaogaina o le eletise ma le taimi nei e fetaui ma manaʻoga, siosiomaga. tulaga, faʻapipiʻi faʻapipiʻi faʻaogaina faʻatagaina e galue i le tele, faʻaogaina o le voltage range, mana faʻaaogaina ma le voluma ma isi mea e faʻafetaui ai manaʻoga.Mo se faʻataʻitaʻiga, mo le faʻalauteleina o faʻailoga AC e pei o leo ma le vitio, e sili atu ona talafeagai le filifilia o se faʻamalosi faʻaogaina ma se fua tele o le liua;mo le fa'agaioiina o fa'ailo vaivai DC, e sili atu ona talafeagai le filifilia o se fa'auma fa'agaioiga ma maualuga le sa'o (fa'atusa, o le fa'amalo o le taimi nei, detuning voltage, ma le vevela e la'ititi lava).
(3) Aʻo leʻi faʻaaogaina, e tatau ona malamalama i vaega ma laina eletise o faʻasalalauga faʻapipiʻi faʻapipiʻi, ma ia faʻamalamalamaina le pepa faʻapipiʻi, faʻasologa o taʻitaʻi fafo, faʻamau faʻamau, laina eletise eletise, ma isi.
(4) E tatau ona fa'afeso'ota'i le feso'ota'iga de-vibration pe a mana'omia, i le amanaia o le bandwidth i luga o le nofoaga e mafai ona de-vibrate.
(5) O le faʻapipiʻi faʻapipiʻi faʻaogaina o le autu lea o le eletise eletise, ina ia faʻaitiitia le faʻaleagaina, e tatau ona faia ni puipuiga talafeagai.
Fa'ailoga ma Ta'iala
Fa'ailoga filifilia o mea fa'aola fa'agaioiga ma ta'iala mo le fa'aogaina
I le faʻataʻitaʻiga, e tatau ona faʻaaogaina faʻamalositino faʻapitoa i le mamao e mafai ai, aua e faigofie ona maua ma taugofie, naʻo le taimi lava e le mafai ai e le ituaiga faʻamoemoega lautele ona ausia manaʻoga, e mafai ona faʻaaogaina le ituaiga faʻapitoa, lea e mafai ona faʻaitiitia ai tau, ae faigofie foi ona mautinoa le sapalai.
Faʻatasi ai ma le atinaʻeina o tekinolosi matua, o le faʻaogaina o le faʻaogaina o mea faʻapipiʻi ua faʻateleina ma faʻateleina, ma i le feagai ai ma ituaiga eseese o faʻamalosi faʻagaioiga, o loʻo i ai ni faʻatonuga masani masani mo la latou filifiliga.Ole filifiliga lea e fa'amalieina mana'oga, ae fa'apea fo'i le fa'asaoina o fa'amatalaga fa'amatalaga na faia se sao tele.O fa'ailoga filifilia e masani ona fa'aaoga e:
O le laasaga muamua o le filifilia lea o le voltage.Talu ai o le tele o mea fa'apipi'i e gaosia mo mea tau alamanuia e ± 15V, ae a manatu e tatau ona fa'atupuina mo masini fa'aogaina i le 3V (po'o lalo ifo o le 5V), o lenei ± 15V fa'asologa e mafai ona le aofia ai.E le gata i lea, o le filifiliga o le a le afifi ma le tau e tatau ona faʻavae i luga o manaʻoga.
Sa'o Fa'atatau i le fesuiaiga o le fa'aogaina o le voltage detuning (Vos) ma lona fa'afefeteina o le vevela fa'atasi ma le PSRR ma le CMRR.
Gain Bandwidth Product (GBW) O le bandwidth gain o se ituaiga voltage feedback type gain op-amp e fuafua ai le bandwidth aoga i se tusi talosaga.
Le fa'aogaina o le malosi (LQ mana'omia) O se mataupu taua i le tele o talosaga.Talu ai e iai le malosi o le fa'aogaina o mea fa'aola e iai se a'afiaga tele i le tufatufaina atu o le paoa o le faiga atoa, o le fa'amalieina o le taimi nei o se fa'ata'ita'iga taua tele, aemaise lava i fa'aoga e fa'aogaina maa.
O le fa'aituau o lo'o i ai nei (LB) e mafai ona a'afia e le fa'apogai po'o le fa'alavelave fa'afofoga ma e mafai ona i'u ai i fa'alavelave fa'aletonu.O talosaga e maualuga le fa'apogai po'o le maualuga o le fa'aogaina o elemene (e pei o le transimpedance amplifiers po'o le tu'ufa'atasia) e masani ona mana'omia ai le fa'aituau maualalo;O mea fa'aoga FET ma CMOS op amps e masani lava ona maua ai le fa'aituau maualalo maualalo.
Ole tele ole afifi e fa'alagolago ile talosaga ma ole op-amp e filifilia e fetaui ma mana'oga o le afifi.
Tulaga lelei
Tulaga lelei o fa'amoemoega lautele op amps
O faʻamanuiaga autu o le tau maualalo, faʻamatalaga talafeagai ma le tele o filifiliga o oloa.
Talosaga
Fa'aoga o fa'amoemoega lautele op amps
Ona o latou lava uiga, latou te faʻaaogaina i le tele o faʻaoga.O fa'aoga autu o lo'o i ai tulaga mana'oga fa'apitoa e feololo.Ina ia fa'amalieina mana'oga o galuega, e fa'amanuiaina le tamaoaiga ma le fa'atinoga.O op amps fa'apipi'i fa'amoemoe lautele e fetaui lelei mo le fa'ateleina o fa'ailoga maualalo.
