OPAMP (741 Hom) THIAB 555 TESTER

OPAMPS thiab 555 timers yog ib qho ntawm cov siv hluav taws xob ICs uas peb siv tas li, Yog li peb yuav tsum ua kom ntseeg tau tias ICs ua haujlwm tau raug lossis ua tsis raug. Yog li peb yuav tsum ua tus ntsuas uas yuav pab peb ntsuas seb cov ICs ua haujlwm tau zoo. Yog tias tus ntsuas ntsuas tsis muab cov txiaj ntsig xav tau, tom qab ntawd IC tuaj yeem ua tsis raug thiab xav tau hloov pauv. Yog li ntawd tus tester yuav tsum tau ua thiab yuav tsum tau nqa tau thiab nqa tau.

Ntawm no peb txiav txim siab tsuas yog 741 OPAMP IC hom thiab sib npaug. Thiab tus qauv 555 timer IC. Ob leeg yuav tsum yog hauv DIP (Dual Inline Package) pob raws li lub ntsuas tau ua rau DIP pob nkaus xwb. Yog li cia peb mus txuas ntxiv.

Kauj Ruam 1: Sib Sau Ua Ke

Yam Yuav Tsum Tau Ua:

1. 8 tus pin IC tester ZIF (xoom tso qhov quab yuam) lub qhov (socket), DIP

2.3 LEDs

3. 1 meg, 3 220ohm, 1 100ohm, 2 100khom, 1 1k resistor

4. 1 10uf, 1 1uf, 1 47uf polar electrolytic capacitor, ntsuas hluav taws xob 16v

5. veroboard thiab cov khoom siv sib txuas

6. 555 thiab 741 (lossis sib npaug) rau kev xeem

7. Breadboard rau kev sim

8. 9v lossis 12v roj teeb

Kauj ruam 2: Ua Circuit Court

Tam sim no sau tag nrho cov khoom siv thiab sim rau ntawm daim ntawv qhia zaub mov. Kuaj ob lub voj voog. Yog tias LEDs ntsais ces IC zoo. Yog tias LED tsis ntsais (tas mus li lossis tawm), ces IC ua haujlwm tsis raug thiab ua tsis raug. Rau 741 muaj 2 LED uas yuav ntsais muag thiab rau 555 muaj ib qho LED uas yuav ntsais xwb. Kuv twb tau sim ntawm lub khob cij ua ntej. Yog li kuv ncaj qha soldered lawv ntawm ib qho ntawm veroboard/ perfboard/ zeroboard.

Tshooj 741 yog qhov ua tau zoo sib txawv uas yuav ntsais muag 2 LEDs ntawm qhov tso tawm.

555 kuj tseem tau teeb tsa ua tus saib xyuas zoo uas yuav ntsais ib qho LED ntawm qhov tso tawm.

Cov ncauj lus kom ntxaws, Circuit Court tau muab rau hauv Pics txuas ntawm no.

Kev siv hluav taws xob tuaj yeem khiav tau yooj yim siv roj teeb 9V lossis roj teeb 12V.

Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm astable multivibrator tuaj yeem nrhiav tau yooj yim hauv google.

Kauj ruam 3: Thaum kawg…

Thaum kawg…

Tom qab soldering lub Circuit Court yuav zoo li no. Thiab qhov txuas video:

qhia yuav muab pov thawj tias ICs uas peb tau coj los lawm. Yog LEDs ntsais ces IC zoo. Yog tias LED tsis ntsais (tas mus li lossis tawm), ces IC ua haujlwm tsis raug thiab ua tsis raug. Rau 741 muaj 2 LED uas yuav ntsais muag thiab rau 55 muaj ib qho LED uas yuav ntsais xwb. Qhov ib nrab yog rau 741 thiab ib nrab yog rau 555. Xwb, 2 LED ntu yog rau 741 thiab ib ntu LED yog rau 555. Nws tseem pom meej los ntawm koj daim duab qhia chaw. Yog li sim tag nrho koj li 555 thiab 741 hom. Zoo siab mus ncig.

Nco tseg- 741 hom thiab sib npaug- TL071, NE5534, OP07, CA3140, MCP601, thiab lwm yam.
