Taw qhia

LTspice yog SPICE simulation software pub dawb pub dawb nrog cov duab pom zoo, lub ntsej muag saib pom, thiab ntau yam kev txhim kho uas ua haujlwm ntawm ob qho tib si Windows thiab Mac OS X. Kuv siv nws los tshawb fawb tus cwj pwm hauv Circuit Court thiab sim sai nrog cov khoom siv hluav taws xob tshiab rau kuv lab ua ntej prototyping PCB (Luam tawm) Circuit Board) tsim. Txoj kev kawm nkhaus yog ib qho yooj yim kom kov yeej ua tsaug rau kev txhawb nqa los ntawm Analog Devices, Yahoo's LTspice Support Group thiab nws kev sib raug zoo nrog ntau hom SPICE qauv muab los ntawm cov neeg muag khoom nti.

Cov Lus Qhia no yuav ua pov thawj yuav ua li cas mus dhau cov ntawv qiv khoom siv nrog LTspice los ntawm kev koom ua ke LMV321 op-amp tus qauv los ntawm peb tus neeg muag khoom sib txawv los tsim lub suab nrov yooj yim raws li qhia hauv daim duab. Txhua ntawm cov qauv no hais txog cov txheej txheem sib txawv muaj nyob hauv LTspice rau siv nrog ntau yam ntawm cov qauv kev tiv thaiv muab los ntawm ntau lub vev xaib muag khoom. Txhua ntawm cov qauv no nthuav qhia kev ua haujlwm sib txawv ib yam nkaus. Txhawm rau hais txog cov teeb meem kev ua tau zoo no kuv rov siv peb tus qauv no nyob rau tam sim no-rau-Voltage tsim ib yam.

Cov neeg tuaj saib lub hom phiaj yog cov uas muaj qee qhov kev paub dhau los tso cov khoom ntawm cov txheej txheem thiab ua haujlwm simulation. Los ntawm qhov kawg ntawm qhov kev qhia no koj yuav paub txhais li cas. SUBCKT cov lus txib hauv cov qauv tsim khoom rau siv nrog LTspice's opamp2 Pin Table thiab Tus kws kho tus cwj pwm kom siv cov khoom tsim khoom hauv koj qhov kev sim.

Kauj Ruam 1: Rub tawm SPICE Cov Qauv Muaj rau LMV321 Op-amp Los Ntawm Cov Neeg Muag Khoom Chip thiab Tso Hauv Cov Npe Tshiab

Kev Tsim Khoom SPICE Qauv

Peb yuav suav nrog peb tus qauv txuj ci raws li LMV321 op-amp hauv qhov kev qhia no. Ua raws li qhov kuv qhia cov kauj ruam.

Tsim daim nplaub tshev rau koj yav tom ntej LTspice schematics, cim, thiab qauv. Kuv yuav xa mus rau cov npe no raws li peb cov npe ua haujlwm mus tom ntej.

Mus ntsib cov vev xaib muag khoom nti no txhawm rau rho tawm SPICE qauv rau LMV321 op-amp:

• TI lub vev xaib (siv National Semiconductor PSPICE Model): LMV321
• Maxim Ua Haujlwm Amplifiers Macromodels: LMX321
• STMicroelectronics Macromodels: LMV3x opamp Macromodel

Saib peb daim duab txuas rau cov ntaub ntawv tshwj xeeb kom rub tawm raws li kev sau cov lus qhia no. Yav tom ntej koj yuav tsum tau tshawb nrhiav cov qauv npe yog tias lawv tau txav los ntawm cov neeg muag khoom nti mus rau nplooj ntawv tshiab.

Txog TI thiab STMicro koj yuav luam tus qauv los ntawm rub cov ntawv zip rau hauv koj phau ntawv ua haujlwm. Rau Maxim tus qauv koj yuav nyem-nyem rau ntawm LMX321. FAM cov ntaub ntawv ntawm lawv lub vev xaib thiab khaws nws mus rau koj li LTspice cov npe ua haujlwm.

Qhov kawg ntawm cov kauj ruam no koj yuav tsum muaj peb cov txuj lom qauv ua piv txwv hauv koj phau ntawv teev npe ua haujlwm:

• LMV321. MOD
• LMX321. FAM
• LMV3x_macromodel.mod

Txhua ntawm cov ntaub ntawv no tuaj yeem qhib nrog cov ntawv kho kom pom cov khoom sib xws:

• cov ntaub ntawv saum toj kawg nkaus,
• . SUBCKT hais kom ua,
• txuj lom txib tsim tawm tus qauv.

Kauj Ruam 2: Qhib Generic 5-pin LTspice Opamp2.asy Symbol

Opamp2.asy Yog Reusable

Los ntawm LTspice Cov ntawv qhia zaub mov Qhib lub cim opamp2.asy los ntawm koj cov npe teev npe.

Rau Windows teeb tsa ua ntej qhov no yuav yog:

C -> LTC -> LTspiceXVII -> lib -> sym -> Opamps -> opamp2.asy

Lub cim opamp2 tsis muaj qauv op-amp muab rau nws. Yog li nws yuav tsis khiav hauv simulation. Vim li no nws yog qhov pib zoo pib raws li nws muaj cov duab kos thiab txuas rau peb los tsim ib qho op-amp uas siv tsib tus pin sib xws:

1. Hauv+
2. Hauv-
3. V+ ua
4. V-
5. Tawm

Saib xyuas kom tsis txhob qhib ib qho ntawm cov ntaub ntawv cim zoo sib xws los ntawm kev ua yuam kev:
