Kev xaiv thiab kev thov
Kev xaiv thiab siv cov amplifiers.
Muaj ntau pawg thiab ntau yam ntawm kev sib xyaw ua haujlwm amplifiers, uas yuav tsum tau xaiv kom tsim nyog thiab siv raws li qhov xav tau ntawm kev siv.
(1) Sim siv lub hom phiaj dav dav ua haujlwm ua haujlwm amplifiers.Thaum lub kaw lus siv ntau lub tshuab ua haujlwm, kom deb li deb tau siv ntau lub tshuab ua haujlwm sib txuas ua ke, xws li LM324, LF347, thiab lwm yam. yog plaub lub tshuab ua haujlwm ua haujlwm tau ntim ua ke hauv ib qho kev sib xyaw ua ke.
(2) Qhov kev xaiv tiag tiag ntawm kev sib xyaw ua haujlwm amplifier, tab sis kuj xav txog qhov xwm txheej ntawm lub teeb liab qhov chaw (yog qhov chaw hluav taws xob lossis qhov chaw tam sim no), qhov xwm txheej ntawm cov khoom thauj, kev sib xyaw ua haujlwm amplifier tso zis voltage thiab tam sim no kom tau raws li qhov xav tau, ib puag ncig. tej yam kev mob, kev ua hauj lwm amplifier tso cai rau ua hauj lwm ntau yam, kev khiav hauj lwm voltage range, hwj chim noj thiab ntim thiab lwm yam kom tau raws li qhov yuav tsum tau.Piv txwv li, rau amplifying AC signals xws li suab thiab yees duab, nws yog tsim nyog los xaiv ib tug ua hauj lwm amplifier nrog ib tug loj conversion tus nqi;rau kev ua cov cim tsis muaj zog DC, nws yog qhov tsim nyog los xaiv qhov kev ua haujlwm amplifier nrog qhov raug siab (piv txwv li, qhov ntsuas tam sim no, qhov ntsuas hluav taws xob, thiab qhov kub thiab txias me me).
(3) Ua ntej siv, nws yog ib qho tsim nyog yuav tsum nkag siab txog cov pawg thiab cov khoom siv hluav taws xob ntawm cov khoom siv ua haujlwm sib xyaw ua ke, thiab kom paub meej cov ntaub ntawv pob, kev teeb tsa sab nraud, tus pin thaiv, lub zog hluav taws xob ntau, thiab lwm yam.
(4) Lub de-vibration network yuav tsum tau txuas nrog raws li qhov yuav tsum tau ua, coj mus rau hauv tus account lub bandwidth ntawm qhov chaw uas muaj peev xwm de-vibrate.
(5) Lub tshuab ua haujlwm sib xyaw ua ke yog lub hauv paus ntawm lub tshuab hluav taws xob, txhawm rau txo kev puas tsuaj, kev tiv thaiv tsim nyog yuav tsum tau ua.
Indicators thiab Guidelines
Kev ua haujlwm amplifier xaiv cov ntsuas thiab cov txheej txheem tsim cov ntawv thov
Hauv kev xyaum, lub hom phiaj ua haujlwm dav dav yuav tsum tau siv kom deb li deb tau, vim tias lawv yooj yim kom tau txais thiab raug nqi, tsuas yog thaum hom hom phiaj tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua, tuaj yeem siv hom tshwj xeeb, uas tuaj yeem txo cov nqi, tab sis kuj yooj yim los xyuas kom meej cov khoom.
Nrog rau txoj kev loj hlob ntawm cov cuab yeej cuab tam, daim ntawv thov ntawm kev ua haujlwm amplifiers tau dhau los ua ntau thiab ntau dua, thiab nyob rau hauv lub ntsej muag ntawm ntau hom kev ua haujlwm amplifiers, muaj qee cov lus qhia rau lawv xaiv.Qhov no yog xaiv kom tau raws li qhov yuav tsum tau ua, tab sis kuj yuav txuag tau cov ntaub ntawv los ua lub luag haujlwm zoo.Feem ntau siv cov ntsuas kev xaiv yog:
Thawj kauj ruam yog xaiv qhov voltage.Raws li feem ntau cov amplifiers tsim rau kev lag luam kev siv yog ± 15V, tab sis xav tias lawv yuav tsum tau tsim rau handheld pab kiag li lawm khiav hauj lwm ntawm 3V (los yog qis dua 5V), qhov no ± 15V series yuav raug tshem tawm.Tsis tas li ntawd, qhov kev txiav txim siab ntawm lub pob twg thiab tus nqi yuav tsum yog raws li qhov yuav tsum tau ua.
Precision Feem ntau muaj feem xyuam rau qhov sib txawv ntawm cov tswv yim detuning voltage (Vos) thiab nws cov txheeb ze kub drift li PSRR thiab CMRR.
Gain Bandwidth Product (GBW) Qhov nce bandwidth ntawm qhov kev tawm tswv yim voltage hom nce op-amp txiav txim siab qhov txiaj ntsig bandwidth hauv ib daim ntawv thov.
Kev siv hluav taws xob (LQ yuav tsum tau) Ib qho teeb meem tseem ceeb hauv ntau daim ntawv thov.Raws li kev ua haujlwm amplifiers muaj peev xwm ua rau muaj kev cuam tshuam loj rau kev faib hluav taws xob ntawm tag nrho cov kab ke, quiescent tam sim no yog ib qho tseem ceeb tsim kev xav, tshwj xeeb tshaj yog nyob rau hauv kev siv roj teeb.
Lub tswv yim tsis ncaj ncees tam sim no (LB) tuaj yeem cuam tshuam los ntawm qhov chaw lossis cov lus tawm tswv yim impedance thiab tuaj yeem ua rau muaj qhov yuam kev.Cov ntawv thov uas muaj qhov siab impedance lossis siab impedance tawm tswv yim cov ntsiab lus (xws li transimpedance amplifiers lossis integrators) feem ntau yuav tsum muaj cov kev tawm tswv yim tsis zoo;FET inputs thiab CMOS op amps feem ntau muab cov kev tawm tswv yim qis heev.
Lub pob loj nyob ntawm daim ntawv thov thiab op-amp raug xaiv kom haum raws li qhov xav tau ntawm pob.
Qhov zoo
Qhov zoo ntawm lub hom phiaj dav dav op amps
Qhov zoo tshaj plaws yog tus nqi qis, nruab nrab specifications thiab ntau yam khoom xaiv.
Daim ntawv thov
Kev siv lub hom phiaj dav dav op amps
Vim yog lawv tus kheej cov yam ntxwv, lawv tau siv ntau yam kev siv.Cov ntawv thov tseem ceeb yog qhov uas cov kev xav tau yog nruab nrab.Txhawm rau ua kom tau raws li qhov xav tau ntawm kev ua haujlwm, kev lag luam thiab cov tswv yim yeej.Lub hom phiaj dav dav ua ke op amps yog tsim rau amplifying tsawg zaus cov cim.
