Iimpawu ze-LM339 kunye neempawu zombane

I-LM339 iqulethe iifayile ezine ezizimeleyo ze-voltage.Umthelisi ngamnye usebenza ngokukodwa, ukuqinisekisa ukuba ukusebenza kwesinye akuchaphazeli abanye.Eli nqaku lincitshile uphazamiso lwengxolo phakathi kokuthamba, ebaluleke kakhulu kwimijikelezo ebuthathaka apho imicimbi echanileyo.

I-chip inokusebenza kunye nokunikezelwa kwamandla okanye ukuhanjiswa kwamandla amabini.Ngokubonelela ngoncedo olunye, kusebenza ngaphakathi kuluhlu lwevolthi ye-+3.0 v ukuya +36 v.Iimfuno ziyahluka.

Kwicala lokufaka, i-LM339 yenzelwe ukunciphisa nawuphi na umkhangeli.Igalelo legalelo langoku liphantsi njenge-25 na, enceda kwizicelo apho imizalwane emincinci inokubangela iimpazamo kwinkqubo.Igalelo legalelo langoku liphantsi kakhulu, ± 50 na, ukuphucula imeko ngokuchanekileyo.

I-infting voltage igcinwe iphantsi, uqinisekisa ukuba kwafunyanwa umahluko kwiivolthi ezincinci kakhulu.Uluhlu lwevoti ye-Poltage ye-Poltage yandisa yonke indlela ukuya kuyo yonke indlela ukuya kuthi ga kuyo yonke indlela ukuya kuthi ga kuyo yonke indlela ukuya kuthi ga kuyo yonke indlela ukuya kuyo yonke indlela ukuya kuthi ga kuyo yonke indlela ukuya kwi-LM339 ayinakho ukuphatha imiqondiso eqala kwi-zero volts, nto leyo eyingenelo kwizicelo ezininzi zevolthi ephantsi.

I-LM339 ikwaqhayisa nge-voltage ephantsi ye-Sattiet ephantsi kakhulu, i-130 mV kwi-4.0 ma ilayini yangoku.Oku kubalulekile ukuba kusetyenziswe iivolvathi eziphantsi, kufana nemijikelezo eqhutywa yibhetri, apho ufuna ukunciphisa amandla aphulukene nesixhobo.I-voltage encitshisiweyo iqinisekisa ukuba iziphumo ziya kuhlala zinokusetyenziswa naxa inkqubo isebenza kumandla amancinci.

Esi sixhobo sihambelana ngokupheleleyo ne-TTL kunye ne-CMOS Logic amanqanaba, esenza kube lula ukudibanisa iinkqubo ezahlukeneyo zedijithali ngaphandle kwesidingo sezinto ezongeziweyo okanye inqanaba lokutshintsha kwenqanaba okanye inqanaba lokutshintsha kwenqanaba okanye inqanaba lokutshintsha kwenqanaba okanye inqanaba lokutshintsha kwenqanaba okanye inqanaba lokutshintsha kwenqanaba.

Ukuqinisekisa ukusebenza okuthembekileyo, i-LM339 iquka i-ESD (i-elektrostatic ikhuphe) i-clamps kwigalelo labo.Ezi clamps zikukhusela ifowuni ukuba ikhuphe i-ticket enokuthi iyonakalisa i-chip, onke ngelixa uqinisekisa ukusebenza kwesixhobo esiqhelekileyo.

Ngokwemigangatho yendalo esingqongileyo, i-LM339 yi-PB-ayina-halogn, i-halogn-free, kunye ne-rohs-condliment.Ezi zinto zikwenza ukuba kufundiswe ukhetho olufanelekileyo lwalemidlalo ekufuneka ihlangabezane nemigaqo engqongqo yokhuseleko lokusingqongileyo.

I-LM339 IC I-IC

I Lm339 idla ngokusetyenziswa kwiisekethe apho kufuneka uthelekise imiqondiso emibini yevolthi.Sisixhobo esiguquguqukayo kuba iqulethe iimbalelwano ezahlukeneyo ezahlukileyo, zivumela ukuba zithelekise izibini ezine zeemboniselo ngaxeshanye.Eli nqaku liluncedo ngakumbi kwizicelo apho kufuneka ubeke esweni khona amanqanaba eevolthi ezininzi ngaxeshanye, njengokubeka esweni umbane, ukufunyanwa kwe-voresage, kunye nemisebenzi yokulungisa umqondiso.

Yintoni eyenza i-LM339 ithandwayo phakathi kwabanjineli kunye nezenzo kukudityaniswa kwexabiso eliphantsi kunye nentsebenzo eyomeleleyo.I-chip yenzelwe ukuba ithembeke ngaphandle kokuqhekeza uhlahlo-lwabiwo mali, yiyo loo nto ihamba-hamba kwiiprojekthi ezininzi ze-DIY nakwizicelo zemizi mveliso.Ukusebenza kwayo okuziindleko akuthethi ukuba iyaphalala ekusebenzeni;Ukuthelekisa kubonelela ngesantya esifanelekileyo kunye nokuchaneka koluhlu olubanzi lwemisebenzi.

Ixesha lempendulo le-LM339 likhawuleza ngokwaneleyo ukuze lifezekise iimfuno zezicelo ezininzi.Nokuba uyila isekethe ye-voltage ye-voltage okanye into enzima kakhulu, intsebenzo ye-Ic inokujongana neemfuno zokufumana i-voltage yexesha lokwenyani ngaphandle kokulibaziseka okungabonakaliyo.

Ukusetyenziswa okusebenzayo, ukukwazi ukuthelekisa izibini ezininzi ze-voltage ngexesha kanye kunokuba lula kuyilo lwesekethe kwaye lugcine indawo yeBhodi.Oku kubaluleke ngakumbi kwiinkqubo ezifuna ukuthelekisa imiqondiso emininzi ye-voltage ngokuhambelana nokucela izinto ezahlukileyo kwisibini ngasinye.

Ngokubanzi, i-LM339 inika isisombululo esithe tye, esifanelekileyo sokuthelekisa i-voltage, nokuba kwizicelo ezisisiseko okanye kwimilo ephambili engaphezulu yokufuna ukusebenza ngokukhawuleza nangokuthembekileyo.

Ungayisebenzisa njani i-LM339 yevoti ye-LM339

Makhe siyeke ukusebenza kwe-LM339 ngokujonga isakhiwo sayo sangaphakathi.I-LM339 iqulethe abathathi-nxaxheba abane, oko kuthetha ukuba inokuthelekisa imiqondiso emininzi ye-voltage ngaxeshanye.Umkhangeli ngamnye uqhagamshele ngaphakathi ukuthelekisa i-vollel yevolimo, ukwenza i-IC Isisombululo esiguqulweyo kwizicelo ezahlukeneyo.

Ngoku, masijonge nje omnye wabaqulathe kwaye sakhe isisekelo ngokulula ukuze ubone ukuba isebenza njani.Kuleseto esisisiseko, siya kuthelekisa i-voltagesm yegalelo amabini, v1 kunye ne-V2, kwaye ivelise imveliso esekwe apho i-voltage iphezulu.

Kwezi sekethe, i-LM339 ithelekisa i-Voltsuges ezimbini-v1 kunye ne-v2.Isiphumo sale thelekiso sisiphumo se-VO.Esi sixhobo sixhotyiswe ngumthombo we-voltage enye, i-VCC, njengoko kubonisiwe kumzobo.

I-LM339 isebenza ngolu hlobo lulandelayo:

Ukuba i-V1 inkulu kune-V2, i-VOPE iyonga ikwi-VCC (i-voltage yomsebenzi).

Ukuba i-V2 inkulu kune-v1, i-VOPE ye-VOP iya kuba yi-0V (okanye i-GNN).

Oku kuseta kuluncedo ekumiseleni ukuba yeyiphi kwezi votmpos ezimbini ziphezulu.Iziphumo (i-VO) zibonisa ngokuthe ngqo iziphumo zothelekiso.Iziphumo eziphezulu (VCC) zibonisa ukuba i-V1 iphezulu, ngelixa ikhutshiwe (0V) kuthetha i-V2 iphezulu.

Xa usakha esi sekethe kwisicelo sehlabathi lokwenyani, uya kuqaphela ukuba iziphumo ze-LM339 "zicocekile" kwaye ziphendule ngokukhawuleza ukuba zitshintshe i-inftage yegalelo.Kubalulekile ukuba uqiniseke ukuba zombini iivolomu zegalelo (v1 kunye ne-V2) zikuluhlu oluchaziweyo lokuhambelana ngokuchanekileyo.Ukuba igalelo lingaphezulu kwemida yokusebenza, inokukhokelela kuthelekiso olungachanekanga okanye ukonakala kwi-IC.
