Umphumela

Indima yama-voltage reference chips.

Phakathi kwebanga lamanje elilinganiselwe, ukunemba kwedivayisi yomthombo wamandla kagesi eyireferensi (ukuchezuka kwevelu ye-voltage, ukukhukhuleka, izinga lokulungiswa kwamanje, namanye amapharamitha ezinkomba) kungcono kakhulu kune-zen regulator diode evamile noma isilawuli samatheminali amathathu, ngakho-ke isetshenziswa esidingweni se-voltage yereferensi enembayo ephezulu njenge-voltage eyireferensi, ngokuvamile ku-A/D, D/A, kanye nomthombo wamandla kagesi anembe kakhulu, kodwa futhi amanye amasekhethi okuqapha ama-voltage nawo asebenzisa umthombo we-voltage eyireferensi.

Ukwahlukanisa

Ukuhlukaniswa kwe-voltage reference chips.
Ngokusho kwereferensi yangaphakathi, ukwakheka kwe-voltage yehlukile, ireferensi kagesi ihlukaniswe ngereferensi ye-bandgap voltage kanye nereferensi ye-voltage regulator voltage izigaba ezimbili.Isakhiwo sereferensi ye-voltage yegebe yebhendi iyisihlukaniso se-PN echemile phambili kanye ne-voltage ehlotshaniswa ne-VT (amandla ashisayo) ochungechungeni, kusetshenziswa i-coefficient yezinga lokushisa elingalungile le-PN junction kanye ne-coefficient yezinga lokushisa elihle le-VT offset ukuze kufinyelelwe isinxephezelo sezinga lokushisa.Isakhiwo sereferensi ye-voltage yesilawuli iwuchungechunge lokuxhunywa kwesilawuli sokuqhekeka kobuso obungaphansi komhlaba kanye nokuhlangana kwe-PN, kusetshenziswa i-coefficient yezinga lokushisa eliphozithivu yesilawuli kanye ne-coefficient yezinga lokushisa elingalungile ye-PN junction ukuze kukhanselwe isinxephezelo sezinga lokushisa.Ukuhlukaniswa kwendawo engaphansi kusiza ukunciphisa umsindo.I-voltage yereferensi yereferensi ye-tube voltage iphezulu (cishe i-7V);i-voltage eyireferensi yereferensi ye-bandgap voltage iphansi, ngakho-ke yakamuva isetshenziswa kabanzi lapho kudingeka khona ama-voltages aphansi.
Ngokuya ngesakhiwo sohlelo lwangaphandle, izinkomba ze-voltage zihlukaniswe izigaba ezimbili: uchungechunge nokuhambisana.Uma isetshenziswa, izinkomba zamandla kagesi eziwuchungechunge zifana nezinto zamandla ezilawulwa ngamatheminali amathathu, lapho i-voltage eyireferensi ixhunywe ochungechungeni nomthwalo;izinkomba ze-parallel voltage zifana nezilawuli zikagesi, lapho i-voltage eyireferensi ixhunywe ngokuhambisana nomthwalo.Kokubili izinkomba ze-band gap voltage nereferensi ye-tube voltage zingasetshenziswa kulokhu kucushwa okubili.Inzuzo yereferensi ye-voltage yochungechunge ukuthi idinga kuphela ukunikezwa kokufaka ukuze kuhlinzekwe i-current ethule ye-chip futhi inikeze umthamo wamanje uma umthwalo ukhona;izinkomba zamandla kagesi afanayo zidinga ukuthi isethi yamanje echemayo ibe nkulu kunesamba samanje esithule wechip kanye nomthamo omkhulu wamanje wokulayisha futhi azifanele ukusetshenziswa kwamandla aphansi.Izinzuzo zamareferensi kagesi afanayo ukuthi achemile njengamanje, angakwazi ukubhekelela inhlobonhlobo yama-voltage okokufaka, futhi alungele ukusetshenziswa njengereferensi yamandla kagesi amisiwe.

Ukukhetha

Ukukhethwa kochungechunge lwereferensi ye-voltage chip ne-parallel voltage reference chip
Ireferensi ye-voltage yochungechunge inamatheminali amathathu: i-VIN, i-VOUT, ne-GND, efana nesilawuli somugqa, kodwa esinomphumela ophansi wamanje nokunemba okuphezulu kakhulu.Amareferensi kagesi ochungechunge axhunywe ngokwesakhiwo ochungechungeni nomthwalo (Umfanekiso 1) futhi angasetshenziswa njengesixazululi esilawulwa ugesi esitholakala phakathi kwamatheminali e-VIN kanye ne-VOUT.Ngokulungisa ukumelana kwayo kwangaphakathi, umehluko phakathi kwenani le-VIN kanye nokwehla kwe-voltage kuyo yonke i-resistor yangaphakathi (elingana ne-voltage yereferensi ku-VOUT) igcinwa izinzile.Njengoba ugesi udingeka ukuze ukhiqize ukwehla kwamandla kagesi, idivayisi idinga ukudweba inani elincane lamanje elithule ukuze kuqinisekiswe ukulawulwa kwamandla kagesi ngaphandle komthwalo.Amareferensi kagesi axhumeke ngochungechunge anezici ezilandelayo.
- I-voltage yokunikezela (VCC) kufanele ibe phezulu ngokwanele ukuze kuqinisekiswe ukwehla kwe-voltage eyanele kuzo zonke izinto eziphikisayo zangaphakathi, kodwa i-voltage ephezulu kakhulu ingalimaza idivayisi.
- Idivayisi kanye nephakheji yayo kufanele ikwazi ukuqeda amandla weshubhu yesilawuli sochungechunge.
- Ngaphandle komthwalo, ukuphela kwamandla okuphela kwamandla amandla athule wereferensi kagesi.
- Amareferensi kagesi ochungechunge ngokuvamile anephutha lokuqala elingcono kanye nama-coefficients okushisa kunereferensi ye-voltage efanayo.

I-parallel voltage reference inamatheminali amabili: OUT kanye ne-GND.Iyafana ngokomthetho ne-voltage regulator diode kodwa inezici ezingcono zokulawula i-voltage, efana ne-voltage diode elawula i-voltage edinga i-resistor yangaphandle futhi esebenza ngokuhambisana nomthwalo (Umfanekiso 2).Ireferensi yamandla kagesi afanayo ingasetshenziswa njengomthombo wamanje olawulwa amandla kagesi oxhunywe phakathi kwe-OUT ne-GND, ngokulungisa amandla angaphakathi ukuze umehluko phakathi kwe-voltage yokuhlinzeka kanye nokwehla kwamandla kagesi ku-resistor R1 (elingana ne-voltage eyireferensi ku-OUT) ezinzile.Faka enye indlela, ireferensi yohlobo lwe-voltage ehambisanayo igcina i-voltage engaguquki ku-OUT ngokugcina isamba somthwalo wamanje kanye nowamanje ogeleza ku-voltage reference njalo.Izinkomba zohlobo oluhambisanayo zinezici ezilandelayo.
- Ukukhethwa kwe-R1 efanelekile kuqinisekisa ukuthi izidingo zamandla ziyahlangatshezwa futhi ireferensi yohlobo oluhambisanayo lwe-voltage ayinamkhawulo ku-voltage enkulu yokuhlinzeka.
- Isilinganiso esiphezulu samanje esihlinzekwa yisiphakeli sizimele kumthwalo kanye namandla okuphakela ageleza phakathi komthwalo futhi isithenjwa sidinga ukukhiqiza ukwehla kwamandla kagesi afanelekile ku-resistor R1 ukuze kugcinwe i-voltage ye-OUT engashintshi.
- Njengamadivaysi amatheminali angu-2 alula, amareferensi kagesi afanayo angahlelwa abe amasekhethi anoveli afana nezilawuli zamandla kagesi ezingezinhle, izilawuli zaphansi ezintantayo, amasekhethi okusika, namasekhethi akhawulelayo.
- Izinkomba zamandla kagesi afanayo ngokuvamile ziba namandla aphansi okusebenza kunezikhombo zamandla kagesi ochungechunge.
Uma umehluko phakathi kochungechunge namareferensi kagesi afanayo usuqondwa, idivayisi efaneleke kakhulu ingakhethelwa uhlelo oluthile.Ukuze uthole idivayisi efaneleke kakhulu, kungcono ukucabangela kokubili uchungechunge nezinkomba ezifanayo.Uma amapharamitha azo zombili izinhlobo esebaliwe ngokuqondile, uhlobo lwedivayisi lunganqunywa futhi ezinye izindlela ezisetshenziswayo zinikezwa lapha.
- Uma kudingeka ukunemba kokuqala okungaphezulu kuka-0.1% kanye ne-coefficient yezinga lokushisa engu-25ppm, ireferensi yohlobo lochungechunge lwe-voltage kufanele ngokuvamile ikhethwe.
- Uma kudingeka ukusebenza kwamanje okuphansi kakhulu, kufanele kukhethwe ireferensi ye-voltage efanayo.
- Kufanele kuqashelwe uma kusetshenziswa izinkomba zamandla kagesi afanayo anama-voltage anikezelayo abanzi noma imithwalo emikhulu eguquguqukayo.Qiniseka ukuthi ubala inani elilindelekile lamandla ahlakaziwe, elingase libe phezulu kakhulu kunereferensi kagesi yochungechunge ngokusebenza okufanayo (bona isibonelo ngezansi).
- Ezinsizeni lapho i-voltage yokuhlinzeka ingaphezu kuka-40V, ireferensi yamandla kagesi afanayo ingaba ukuphela kwenketho.
- Izinkomba zamandla kagesi afanayo zivame ukucatshangelwa lapho kwakhiwa izilawuli zamandla kagesi ezingezinhle, izilawuli zaphansi ezintantayo, amasekhethi okusika, noma amasekhethi akhawulayo.
