nyhuv

Lub luag haujlwm ntawm voltage siv chips.

Nyob rau hauv qhov ntsuas kev khiav hauj lwm tam sim no, qhov tseeb ntawm cov khoom siv hluav taws xob siv hluav taws xob (qhov sib txawv ntawm tus nqi voltage, drift, tam sim no hloov pauv tus nqi, thiab lwm yam ntsuas qhov ntsuas) yog qhov zoo dua li qhov zoo tib yam ntau zen regulator diode los yog peb-terminal regulator, yog li nws yog siv nyob rau hauv kev xav tau rau high-precision siv voltage raws li ib tug siv voltage, feem ntau rau A / D, D / A, thiab high-precision voltage qhov chaw, tab sis kuj muaj ib co voltage xyuas circuits kuj siv qhov siv voltage qhov chaw.

Kev faib tawm

Kev faib tawm ntawm cov khoom siv hluav taws xob siv hluav taws xob.
Raws li kev siv sab hauv, cov qauv tsim hluav taws xob sib txawv, qhov kev siv hluav taws xob tau muab faib ua bandgap voltage siv thiab voltage regulator voltage siv ob pawg.Band sib txawv voltage siv qauv yog ib tug pem hauv ntej-biased PN hlws ris thiab ib tug voltage txuam nrog VT (thermal muaj peev xwm) nyob rau hauv series, siv qhov tsis zoo kub coefficient ntawm PN hlws ris thiab qhov zoo kub coefficient ntawm VT offset kom tiav kub them.Lub regulator voltage siv qauv yog ib tug series ntawm kev sib txuas ntawm sub-surface breakdown regulator thiab PN hlws ris, siv qhov zoo kub coefficient ntawm tus regulator thiab qhov kub tsis zoo coefficient ntawm PN hlws ris kom tshem tawm qhov kub thiab txias.Sub-surface breakdown pab txo cov suab nrov.Kev siv hluav taws xob ntawm lub raj siv hluav taws xob yog siab dua (kwv yees 7V);qhov siv voltage ntawm bandgap voltage siv yog qis dua, yog li tom kawg yog siv ntau dua qhov twg cov khoom siv hluav taws xob tsawg yuav tsum tau siv.
Nyob ntawm cov qauv siv sab nraud, cov ntaub ntawv siv hluav taws xob tau muab faib ua ob pawg: series thiab parallel.Thaum ua ntawv thov, series voltage references zoo ib yam li peb-terminal tswj fais fab mov, qhov twg cov ntaub ntawv voltage yog txuas nrog series nrog lub load;parallel voltage references zoo ib yam li voltage regulators, qhov twg cov reference voltage txuas nyob rau hauv parallel nrog lub load.Ob qhov band gap voltage references thiab tube voltage references tuaj yeem siv rau hauv ob qho kev teeb tsa no.Qhov kom zoo dua ntawm cov kev siv hluav taws xob series yog tias lawv tsuas yog xav tau cov khoom siv nkag los muab cov quiescent tam sim no ntawm cov nti thiab muab cov khoom thauj tam sim no thaum lub sijhawm thauj khoom;parallel voltage references xav tau qhov kev tsis ncaj ncees tam sim no ntau dua li qhov sib npaug ntawm cov nti quiescent tam sim no thiab qhov siab tshaj plaws thauj khoom tam sim no thiab tsis haum rau kev siv hluav taws xob tsawg.Qhov zoo ntawm kev siv hluav taws xob sib txuas yog tias lawv muaj kev tsis ncaj ncees tam sim no, tuaj yeem ua rau ntau yam ntawm cov khoom siv hluav taws xob, thiab tsim nyog siv raws li cov ntaub ntawv pov thawj hluav taws xob.

Kev xaiv

Kev xaiv ntawm series voltage reference chip thiab parallel voltage reference chip
Ib qho hluav taws xob siv hluav taws xob muaj peb lub ntsiab lus: VIN, VOUT, thiab GND, zoo ib yam li cov kab hluav taws xob, tab sis nrog cov zis qis dua tam sim no thiab qhov tseeb heev.Series voltage references yog structurally txuas nyob rau hauv series nrog lub load (Daim duab 1) thiab yuav siv tau raws li ib tug voltage-tswj resistor nyob nruab nrab ntawm VIN thiab VOUT terminals.Los ntawm kev kho nws cov kev tiv thaiv sab hauv, qhov sib txawv ntawm tus nqi VIN thiab qhov hluav taws xob poob thoob plaws hauv lub resistor (sib npaug rau qhov siv hluav taws xob ntawm VOUT) yog ruaj khov.Raws li qhov tam sim no tsim nyog los tsim kom muaj qhov poob qis, cov cuab yeej yuav tsum tau kos ib qho me me ntawm cov quiescent tam sim no kom ntseeg tau tias muaj kev tswj hwm qhov hluav taws xob tsis muaj kev thauj khoom.Series-connected voltage references muaj cov yam ntxwv hauv qab no.
- Cov khoom siv hluav taws xob (VCC) yuav tsum siab txaus kom ntseeg tau tias qhov hluav taws xob txaus poob thoob plaws hauv cov resistors, tab sis qhov hluav taws xob siab dhau tuaj yeem ua rau lub cuab yeej puas.
- Cov cuab yeej thiab nws cov pob yuav tsum muaj peev xwm dissipate lub zog ntawm series regulator raj.
- Thaum tsis muaj load, tsuas yog lub zog dissipation yog qhov quiescent tam sim no ntawm qhov siv hluav taws xob.
- Series voltage references feem ntau muaj qhov yuam kev thawj zaug zoo dua thiab qhov kub thiab txias coefficients dua li cov ntaub ntawv sib txuas.

Kev siv hluav taws xob sib luag muaj ob lub ntsiab lus: OUT thiab GND.Nws yog qhov zoo sib xws rau lub zog tswj hluav taws xob diode tab sis muaj cov yam ntxwv ntawm kev tswj hluav taws xob zoo dua, zoo ib yam li lub tshuab hluav taws xob hluav taws xob uas yuav tsum tau muaj kev tiv thaiv sab nraud thiab ua haujlwm sib npaug nrog cov khoom thauj (Daim duab 2).Kev siv hluav taws xob sib txuas tuaj yeem siv los ua qhov ntsuas hluav taws xob tam sim no txuas ntawm OUT thiab GND, los ntawm kev kho cov tam sim no sab hauv kom qhov sib txawv ntawm cov khoom siv hluav taws xob thiab qhov hluav taws xob poob hla resistor R1 (sib npaug rau qhov siv hluav taws xob ntawm OUT) tseem nyob. ruaj khov.Muab lwm txoj hauv kev, qhov sib npaug ntawm cov khoom siv hluav taws xob siv hluav taws xob tswj xyuas qhov hluav taws xob tas li ntawm OUT los ntawm kev ua kom cov lej ntawm cov khoom thauj tam sim no thiab cov tam sim no ntws los ntawm qhov siv hluav taws xob tas li.Parallel type references muaj cov yam ntxwv hauv qab no.
- Kev xaiv ntawm R1 tsim nyog ua kom ntseeg tau tias lub zog yuav tsum tau ua tiav thiab qhov kev siv hluav taws xob sib txuas tsis muaj qhov txwv ntawm qhov siab tshaj plaws ntawm cov khoom siv hluav taws xob.
- Qhov siab tshaj plaws tam sim no muab los ntawm cov khoom siv yog ywj pheej ntawm kev thauj khoom thiab cov khoom siv tam sim no ntws los ntawm kev thauj khoom thiab cov ntaub ntawv siv yuav tsum tsim kom muaj qhov tsim nyog voltage poob hla resistor R1 kom tswj tau qhov hluav taws xob tsis tu ncua.
- Raws li yooj yim 2-terminal devices, parallel voltage references can be configured in new circuits such as negative voltage regulators, floating ground regulators, clipping circuits, and limiting circuits.
- Parallel voltage references feem ntau muaj qis dua kev khiav hauj lwm tam sim no dua li cov ntaub ntawv siv hluav taws xob.
Thaum qhov sib txawv ntawm cov kab sib txuas thiab cov kab hluav taws xob sib txuas tau nkag siab, cov cuab yeej tsim nyog tshaj plaws tuaj yeem xaiv rau daim ntawv thov tshwj xeeb.Yuav kom tau txais cov cuab yeej tsim nyog tshaj plaws, nws yog qhov zoo tshaj plaws los xav txog ob qho tib si series thiab cov ntaub ntawv sib txuas.Thaum cov kev txwv rau ob hom tau raug xam tshwj xeeb, hom ntaus ntawv tuaj yeem txiav txim siab thiab qee qhov kev qhia pom tau muab rau ntawm no.
- Yog tias qhov tseeb thawj zaug siab dua 0.1% thiab qhov ntsuas kub ntawm 25ppm yuav tsum tau, feem ntau yuav tsum tau xaiv cov khoom siv hluav taws xob.
- Yog tias qhov kev khiav hauj lwm qis tshaj plaws yog qhov yuav tsum tau ua, ces qhov kev siv hluav taws xob sib txuas yuav tsum raug xaiv.
- Kev saib xyuas yuav tsum tau ua thaum siv cov khoom siv hluav taws xob sib txuas nrog cov khoom siv dav dav lossis cov khoom siv hluav taws xob loj.Nco ntsoov xam qhov xav tau ntawm lub zog dissipated, uas tej zaum yuav muaj txiaj ntsig ntau dua li cov kev siv hluav taws xob sib txuas nrog tib qho kev ua tau zoo (saib piv txwv hauv qab).
- Rau cov ntawv thov uas qhov khoom siv hluav taws xob siab dua 40V, qhov kev siv hluav taws xob sib txuas yuav yog tib txoj kev xaiv.
- Parallel voltage references feem ntau yog txiav txim siab thaum tsim tsis zoo voltage regulators, floating hauv av regulators, clipping circuits, los yog limiting circuits.
