Ukukhetha kunye nesicelo

Ukukhethwa kunye nokusetyenziswa kweamplifiers.
Kukho iindidi ezininzi kunye neentlobo ze-amplifiers ezidibeneyo zokusebenza, ezimele zikhethwe ngokufanelekileyo kwaye zisetyenziswe ngokuhambelana neemfuno zangempela zokusetyenziswa.
(1) Zama ukusebenzisa i-amplifiers edibeneyo yokusebenza enenjongo ngokubanzi.Xa inkqubo isebenzisa ii-amplifiers ezisebenzayo ezininzi, kangangoko kunokwenzeka ukusebenzisa iisekethe ezidibeneyo ze-amplifier ezisebenzayo, ezifana ne-LM324, LF347, njl. zi-amplifiers ezine zokusebenza ezipakishwe kunye kwisekethe edibeneyo.
(2) Olona khetho lwe-amplifier yokusebenza edibeneyo, kodwa kwakhona qwalasela ubume bomthombo womqondiso (ngumthombo wamandla ombane okanye umthombo wangoku), uhlobo lomthwalo, umbane odibeneyo wokusebenza kweamplifier ophumayo kunye nomsinga ukuhlangabezana neemfuno, indalo esingqongileyo. iimeko, iamplifier yokusebenza edibeneyo evunyelweyo ukuba isebenze uluhlu, uluhlu lwamandla ombane osebenzayo, ukusetyenziswa kwamandla kunye nomthamo kunye nezinye izinto ukuhlangabezana neemfuno.Ngokomzekelo, ukukhulisa iimpawu ze-AC ezifana ne-audio kunye nevidiyo, kulungele ngakumbi ukukhetha i-amplifier yokusebenza kunye nesantya esikhulu sokuguqulwa;ekusetyenzweni kweempawu ze-DC ezibuthathaka, kukufaneleke ngakumbi ukukhetha iamplifier esebenzayo ngokuchaneka okuphezulu (okt, i-detuning current, i-voltage yokususa, kunye nokukhukuliseka kobushushu zincinci ngokwentelekiso).
(3) Ngaphambi kokusetyenziswa, kuyimfuneko ukuqonda iindidi kunye neeparitha zombane ze-amplifiers ezidibeneyo zokusebenza, kunye nokucacisa ifom yephakheji, ilungiselelo elikhokelayo langaphandle, i-pin wiring, uluhlu lwamandla ombane, njl.
(4) Uthungelwano lwe-de-vibration kufuneka ludityaniswe njengoko lufunwa, kuthathelwa ingqalelo i-bandwidth kwisiseko sokukwazi uku-de-vibrate.
(5) I-amplifier yokusebenza edibeneyo ingundoqo yesekethe ye-elektroniki, ukwenzela ukunciphisa umonakalo, amanyathelo okukhusela afanelekileyo kufuneka athathwe.

Izalathisi kunye neziKhokelo

Iimpawu zokukhetha i-amplifier yokusebenza kunye nezikhokelo zoyilo lwesicelo
Ngokwenza umsebenzi, i-amplifiers yokusebenza yenjongo jikelele kufuneka isetyenziswe ngokusemandleni, kuba kulula ukuyifumana kwaye ixabisa imali, kuphela xa uhlobo lwenjongo jikelele alukwazi ukuhlangabezana neemfuno, lunokusebenzisa uhlobo olukhethekileyo, olunokunciphisa iindleko. kodwa kwakhona kulula ukuqinisekisa unikezelo.
Ngophuhliso lwetheknoloji evuthiweyo, ukusetyenziswa kwe-amplifiers yokusebenza kuya kuxhaphaka ngakumbi, kwaye phambi kweentlobo ezahlukeneyo ze-amplifiers zokusebenza, kukho imiyalelo yezobugcisa eziqhelekileyo zokukhethwa kwazo.Oku kukukhetha ukuhlangabezana neemfuno, kodwa nokugcina imithombo yedatha idlale indima enkulu.Iimpawu zokukhetha eziqhelekileyo ezisetyenziswayo zezi:
Isinyathelo sokuqala kukukhetha i-voltage.Njengoko i-amplifiers ezininzi eziveliswe kwizicelo zemizi-mveliso ziyi-±15V, kodwa ngokuqwalasela ukuba kufuneka ziphuhliselwe izixhobo eziphathwayo ezisebenza kwi-3V (okanye ngaphantsi kwe-5V), olu chungechunge lwe-±15V lungabandakanywa.Ukongezelela, isigqibo sokuba yeyiphi iphakheji kunye nexabiso kufuneka lisekelwe kwiimfuno.
Ukuchaneka Ikakhulu inxulumene nokwahluka kwegalelo lokususa amandla ombane (Vos) kunye nokukhukuliseka kobushushu obunxulumeneyo kunye nePSRR kunye neCMRR.
Imveliso yeGain Bandwidth (GBW) Inzuzo yokufumana i-bandwidth yohlobo lwengxelo yombane ifumana i-op-amp imisela umda oluncedo kwisicelo esinikiweyo.
Ukusetyenziswa kwamandla (imfuneko ye-LQ) Umba obalulekileyo kwizicelo ezininzi.Njengoko i-amplifiers esebenzayo inamandla okuba nempembelelo ebalulekileyo kumandla osasazo lwenkqubo yonke, i-quiescent current yingqwalasela ebalulekileyo yoyilo, ngakumbi kwizicelo ezisebenza ngebhetri.
I-input bias current (LB) inokuphenjelelwa ngumthombo okanye i-impedance yempendulo kwaye ingabangela iimpazamo zokuqhawula.Usetyenziso olunomthombo ophezulu we-impedance okanye i-impedance ephezulu yeempendulo (ezifana ne-transimpedance amplifiers okanye izihlanganisi) zihlala zifuna igalelo eliphantsi le-bias currents;Amagalelo eFET kunye neCMOS op amps ngokubanzi zibonelela ngegalelo elisezantsi kakhulu.
Ubungakanani bephakheji buxhomekeke kwisicelo kwaye i-op-amp ikhethiwe ukuze ihambelane neemfuno zephakheji.
