LMV324IDR Tshiab thawj thaj SOP14 Chip 4 channel tsis tshua muaj hluav taws xob tso zis ua haujlwm amplifier integrated IC Cheebtsam

Raws li cov kev txwv ntawm kev ua haujlwm amplifiers, lawv tuaj yeem muab faib ua pawg hauv qab no.
1, lub hom phiaj dav dav: lub hom phiaj ua haujlwm dav dav yog tsim los rau cov hom phiaj dav dav.Lub ntsiab feature ntawm cov cuab yeej no yog tus nqi qis, cov khoom lag luam ntau, thiab nws cov ntsuas kev ua tau zoo tuaj yeem tsim nyog rau kev siv dav.Piv txwv li μA741 (ib leeg op-amp), LM358 (dual op-amp), LM324 (plaub op-amps), thiab lub raj xa hluav taws xob raws li theem nkag ntawm LF356 yog qhov zoo li no.Tam sim no lawv yog cov feem ntau siv kev ua haujlwm ua haujlwm amplifiers.

2, Siab Resistance Hom
Hom kev ua haujlwm sib xyaw ua ke no yog tus cwj pwm los ntawm qhov sib txawv ntawm hom input impedance thiab cov tswv yim me me tam sim no, feem ntau tshem tawm> 1GΩ ~ 1TΩ, nrog IB ntawm ob peb picoamps rau kaum tawm picoamps.Qhov kev ntsuas tseem ceeb kom ua tiav cov hom phiaj no yog siv cov yam ntxwv ntawm qhov siab input impedance ntawm FETs los tsim qhov sib txawv input theem ntawm op-amp.Nrog FET raws li theem input, tsis tsuas yog siab input impedance, tsis tshua muaj input bias tam sim no, thiab qhov zoo ntawm kev kub ceev, broadband, thiab tsis tshua muaj suab nrov, tab sis lub input detuning voltage yog loj.Cov khoom siv sib xyaw ua ke yog LF355, LF347 (plaub op-amps), thiab ntau dua input impedance CA3130, CA3140, thiab lwm yam.

3, Tsawg-kub drift hom
Nyob rau hauv cov cuab yeej precision, tsis muaj teeb meem nrhiav pom, thiab lwm yam kev tswj tsis siv neeg, nws yog ib txwm xav tias op-amp's detuning voltage yuav tsum me me thiab tsis hloov nrog qhov kub thiab txias.Tsawg kub drifts ua haujlwm amplifiers yog tsim los rau lub hom phiaj no.OP07, OP27, AD508, thiab ICL7650, lub tshuab hluav taws xob qis qis qis uas muaj MOSFETs, yog qee qhov kev ua haujlwm siab, qis-kub-drift ua haujlwm amplifiers hauv kev siv niaj hnub no.

4, High-speed hom
Nyob rau hauv ceev ceev A / D thiab D / A converters thiab video amplifiers, qhov hloov pauv tus nqi SR ntawm kev sib koom ua ke op-amp yuav tsum siab thiab kev sib koom ua ke-tau txais bandwidth BWG yuav tsum loj txaus xws li lub hom phiaj kev sib koom ua ke op-amps tsis haum rau kev siv ceev ceev.Kev kub ceev op-amps feem ntau yog tus cwj pwm los ntawm kev hloov pauv siab thiab cov lus teb dav.Feem ntau op-amps yog LM318, μA715, thiab lwm yam, uas nws SR = 50 ~ 70V / peb, BWG> 20MHz.

5,Tsawg zog siv hom.
Raws li qhov txiaj ntsig zoo tshaj plaws ntawm hluav taws xob hluav taws xob, kev sib koom ua ke yog ua kom yooj yim circuits me me thiab lub teeb yuag, yog li nrog kev nthuav dav ntawm daim ntawv thov ntau yam ntawm cov cuab yeej siv tau yooj yim, nws yog ib qho tsim nyog yuav tsum siv cov khoom siv hluav taws xob tsawg, kev siv hluav taws xob tsawg ntawm kev ua haujlwm amplifier theem siv tau.Cov khoom siv hluav taws xob ua haujlwm feem ntau yog TL-022C, TL-060C, thiab lwm yam, uas nws qhov kev khiav hauj lwm voltage yog ± 2V ~ ± 18V, thiab kev noj tam sim no yog 50 ~ 250μA.Qee cov khoom tau mus txog qib μW, piv txwv li, lub zog ntawm ICL7600 yog 1.5V, thiab lub zog siv yog 10mW, uas tuaj yeem siv tau los ntawm ib lub roj teeb.

6, High voltage thiab siab zog hom
Cov zis hluav taws xob ntawm kev ua haujlwm amplifiers tsuas yog txwv los ntawm lub hwj chim mov.Hauv kev ua haujlwm zoo tib yam amplifiers, qhov siab tshaj plaws tso zis voltage feem ntau tsuas yog ob peb kaum ntawm volts thiab cov zis tam sim no tsuas yog ob peb kaum milliamps.Txhawm rau ua kom cov zis hluav taws xob ntau ntxiv lossis ua kom cov zis tam sim no, kev sib xyaw ua ke op-amp yuav tsum tau muab ntxiv rau sab nraud los ntawm lub koom haum pabcuam.High voltage thiab high tam sim no kev sib xyaw op amps tuaj yeem tso tawm qhov hluav taws xob siab thiab siab tam sim no yam tsis muaj qhov txuas ntxiv.Piv txwv li, D41 kev sib xyaw op-amp tuaj yeem muab qhov hluav taws xob mus txog ± 150V thiab μA791 kev sib xyaw op-amp tuaj yeem xa cov zis tawm mus txog 1A.

7,Programmable tswj hom
Nyob rau hauv tus txheej txheem ntawm instrumentation, muaj ib tug ntau yam teeb meem.Txhawm rau kom tau txais qhov tso tawm qhov hluav taws xob tas li, nws yog qhov yuav tsum tau hloov qhov kev ua haujlwm ntawm lub tshuab ua haujlwm amplifier.Piv txwv li, lub lag luam amplifier muaj qhov loj ntawm 10 zaug, thaum lub teeb liab tawm tswv yim yog 1mv, qhov tso zis hluav taws xob yog 10mv, thaum qhov hluav taws xob input yog 0.1mv, qhov tso zis tsuas yog 1mv, thiaj li yuav tau txais 10mv, qhov magnification yuav tsum yog. hloov mus rau 100. Piv txwv li, PGA103A, los ntawm kev tswj cov qib ntawm tus pin 1,2 hloov lub amplification.
