LMV797MMX / NOPB (Gishya & Umwimerere Mububiko) Imiyoboro Yumuzingi Yuzuzanya IC Electronics Yizewe

ibisobanuro bigufi:

Umuryango wa LMV93x-N (LMV931-N ingaragu, LMV932-N ebyiri na LMV934-N quad) ni voltage nkeya, yongerera ingufu imbaraga.Umuryango LMV93x-N ukora kuva kuri 1.8-V kugeza kuri 5.5-V itanga amashanyarazi kandi ufite gari ya moshi kugeza gari ya moshi.Iyinjiza risanzwe ryumubyigano wagura 200 mV kurenza ibikoresho bifasha abakoresha kongera imikorere irenze itangwa rya voltage.Ibisohoka birashobora guhinduranya gari ya moshi kugeza kuri gari ya moshi zipakuruwe kandi muri mV 105 ziva muri gari ya moshi hamwe na 600-Ω umutwaro kuri 1.8-V.Ibikoresho bya LMV93x-N byateguwe neza kugirango bikore kuri 1.8 V, bigatuma biba byiza kuri selile ebyiri zigendanwa, sisitemu ikoreshwa na bateri na sisitemu imwe ya Li-Ion.

Ibicuruzwa

Ibikoresho bya LMV93x-N byerekana umuvuduko mwiza-wimbaraga, kugera kuri 1.4-MHz byunguka ibicuruzwa byumuvuduko kuri 1.8-V itanga amashanyarazi hamwe numuyoboro muke muto.Ibikoresho bya LMV93x-N birashobora gutwara umutwaro wa 600-and hamwe nu mutwaro wa 1000-pF ufite ubushobozi buke.
Ibi bikoresho kandi bifite inyungu nyinshi za DC zingana na 101 dB, bigatuma zikwiranye na progaramu nkeya-imwe. LMV93x-N imwe itangwa mu kuzigama umwanya-5-pin SC70 na SOT-23.Dual LMV932-N iri mumapaki 8 pin ya VSSOP na SOIC naho quad LMV934-N iri muri 14 pin TSSOP na SOIC
ipaki.Izi paki ntoya nigisubizo cyiza kubutaka bwa PC bwagabanijwe hamwe na elegitoroniki igendanwa nka terefone igendanwa na tableti.

Guhitamo no Gushyira mu bikorwa

Guhitamo no gushyira mubikorwa byongera imbaraga.
Hariho ibyiciro byinshi nubwoko bwibikorwa byongerewe imbaraga, bigomba guhitamo neza kandi bigakoreshwa bijyanye nibisabwa byo gukoresha.
(1) Gerageza gukoresha rusange-intego ihuriweho na amplifier ikora.Iyo sisitemu ikoresha ibyuma byinshi byongera imbaraga, mugihe gishoboka kugirango ukoreshe imiyoboro myinshi ikora ya amplifier ikora, nka LM324, LF347, nibindi nibindi bine byongera imbaraga zipakiye hamwe mukuzunguruka.
. imiterere, ibikorwa byongerewe imbaraga byemerewe gukora murwego rwakazi, ingufu za voltage ikora, gukoresha ingufu nubunini nibindi bintu byujuje ibisabwa.Kurugero, kugirango wongere ibimenyetso bya AC nkamajwi na videwo, birakwiye cyane guhitamo amplifier ikora hamwe nigipimo kinini cyo guhindura;mugutunganya ibimenyetso bya DC bidakomeye, birakwiye cyane guhitamo amplifier ikora ifite ubunyangamugayo buhanitse (nukuvuga, amashanyarazi azimya, guhagarika ingufu, hamwe nubushyuhe bukabije ni bito).

Ibipimo ngenderwaho

Ibikorwa byo guhitamo amplifier yo gutoranya hamwe nubuyobozi bukoreshwa
Mubimenyerezo, ibikorwa-rusange-bigamije ibikorwa byongera imbaraga bigomba gukoreshwa uko bishoboka kwose, kubera ko byoroshye kubona kandi bikoresha amafaranga menshi, gusa mugihe ubwoko rusange-intego rusange idashobora kuzuza ibisabwa, irashobora gukoresha ubwoko bwihariye, bushobora kugabanya ibiciro, ariko kandi byoroshye kwemeza itangwa.
Hamwe niterambere ryikoranabuhanga rikuze, ikoreshwa ryibikorwa byiyongera bigenda byiyongera, kandi imbere yubwoko butandukanye bwibikorwa byongera imbaraga, hariho amabwiriza ya tekiniki asanzwe yo guhitamo kwabo.Nuguhitamo kuzuza ibisabwa, ariko kandi kubika amakuru yatanzwe yagize uruhare runini.Ibipimo byo guhitamo bikunze gukoreshwa ni:
Intambwe yambere nuguhitamo voltage.Nkuko ibyongerwaho byinshi byakozwe mubikorwa byinganda ni ± 15V, ariko urebye ko bigomba gutezwa imbere kubikoresho byabigenewe bikora kuri 3V (cyangwa munsi ya 5V), iyi ser 15V irashobora gukurwaho.Byongeye kandi, icyemezo kijyanye nigipapuro nigiciro bigomba gushingira kubisabwa.
Icyerekezo Cyane cyane kijyanye no guhinduranya kwinjiza voltage (Vos) hamwe nubushyuhe bwayo bugereranije kimwe na PSRR na CMRR.
Kunguka Umuyoboro mugari (GBW) Kwunguka kwaguka kwubwoko bwa voltage ibitekerezo byunguka op-amp igena umurongo mugari mugikorwa runaka.
Gukoresha ingufu (LQ ibisabwa) Ikibazo cyingenzi mubisabwa byinshi.Nka amplifier ikora ifite ubushobozi bwo kugira ingaruka zikomeye mugukwirakwiza amashanyarazi ya sisitemu yose, umutimanama utuje ni ikintu cyiza cyo gutekereza cyane cyane mubikorwa bya batiri.
Iyinjiza ibogamye (LB) irashobora guterwa ninkomoko cyangwa ibitekerezo byangiritse kandi bishobora kuvamo amakosa.Porogaramu ifite inkomoko yo hejuru yingirakamaro cyangwa ibitekerezo byinshi byo gutanga ibitekerezo (nka transimpedance amplifier cyangwa integer) akenshi bisaba kwinjiza bike kubogama;FET yinjiza na CMOS op amps mubisanzwe itanga bike cyane byinjiza kubogama.
Ingano yububiko iterwa na porogaramu kandi op-amp yatoranijwe kugirango ihuze ibisabwa na paki.

Ibyiza

Ibyiza byintego rusange op amps
Ibyiza byingenzi nigiciro gito, ibisobanuro biringaniye hamwe nuburyo butandukanye bwibicuruzwa.

Porogaramu

Gushyira mubikorwa intego rusange op amps
Kubera imiterere yabo bwite, ikoreshwa muburyo butandukanye bwa porogaramu.Porogaramu nyamukuru niho ibisabwa bya tekinike biringaniye.Kugirango uhuze ibikenewe byakazi, ubukungu nibikorwa bifatika.Intego rusange ihuriweho na op amps ikwiranye no kongera ibimenyetso bya frequency nke.
