Rau qhov Op-amp (kev ua haujlwm amplifier) nrog cov lus pom tsis zoo, cov zis yog: A. sib npaug rau cov zis. … Lus qhia: Cov lus teb tsis zoo yog hais txog kev muab cov lus teb rau qhov inverting input davhlau ya nyob twg. Muaj ob hom circuits rau ib qho Op-Amp.
Cov lus teb tsis zoo ua haujlwm li cas hauv op amp?
Ib qho op-amp nrog cov lus pom tsis zoo yuav sim tsav nws cov zis hluav taws xob mus rau qib twg tsim nyog komqhov sib txawv ntawm qhov sib txawv ntawm ob lub tswv yim yog xoom. Qhov siab dua qhov op-amp qhov sib txawv nce, qhov ze dua qhov sib txawv voltage yuav yog xoom.
Cov lus teb tsis zoo yog dab tsi?
Kev tawm tswv yim yog cov txheej txheem uas ib feem ntawm cov teeb liab tso tawm, xws li a voltage lossisib qho tam sim no, yog siv los ua cov tswv yim. Yog tias qhov kev pub rov qab no yog qhov sib txawv ntawm tus nqi lossis theem ("anti-theem") rau lub teeb liab tawm tswv yim, ces cov lus teb tau hais tias yog Cov Lus Qhia Tsis Zoo, lossis cov lus tawm tswv yim degenerative.
Qhov tso zis ntawm op amp yog dab tsi?
Ib qho chaw ua haujlwm amplifier yog ib qho kev sib koom ua ke uas tuaj yeem ua kom muaj zog hluav taws xob tsis muaj zog. Ib qho kev ua haujlwm amplifier muaj ob tus pin input thiab ib tus pin tso zis. Nws lub luag haujlwm tseem ceeb yog txhawm rau nthuav dav thiab tso tawm qhov sib txawv ntawm qhov sib txawv ntawm ob tus pins.
Vim li cas Opamp hu ua 741?
Lub 741 Op Amp IC yog ib qho kev sib koom ua ke monolithic, suav nrog lub hom phiaj dav dav ua haujlwm Amplifier. Nws yog thawj zaug tsim los ntawm Fairchild semiconductors nyob rau hauv lub xyoo 1963. Tus naj npawb 741 qhia tias qhov kev ua haujlwm amplifier IC muaj 7 tus pins ua haujlwm, 4 tus pins muaj peev xwm noj cov tswv yim thiab 1 tus pin tso tawm.
