2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:28

Cov lus qhia no yog txhawm rau tsim Portable Stereo Class-D Audio Power Amplifier siv Texas Instruments Chip TPA3123D2. Koj tuaj yeem siv txoj hauv kev no los sib sau ua ib qho kev npaj ua Amplifier rau hauv ib lub thawv ib yam nkaus. Cov nti no siv cov khoom siv tsawg kawg nkaus thiab yog pob nyiaj siv tus phooj ywg zoo rau ntau yam kev siv. Cov zis ntawm Amplifier nyob ntawm qhov Voltage muab nruab nrab ntawm 10V thiab 30V. Nws tuaj yeem xa 25-W/ch rau hauv 4- Ω Thauj khoom los ntawm 27-V Cov Khoom Siv thiab 20-W/ch rau hauv 4- Ω Thauj khoom los ntawm 24-V Cov Khoom Siv. Yog xav paub ntxiv txog TA3123D2, thov xa mus rau cov ntaub ntawv ntawm

Vim Li Cas Koj Tus Kheej? Koj tuaj yeem hloov kho koj lub Circuit Court raws li xav tau rau koj daim ntawv thov. Nws pab hauv kev kawm thiab xaiv cov khoom zoo. Cov laug cam pheej yig pheej yig yuav cuam tshuam rau qhov zoo ntawm cov khoom siv thiab tej zaum yuav tsis raug kho raws li kev cai tsim.

Qhov Chaw

Capacitors, TA3123D2, thiab Inductors tau yuav los ntawm Mouser Electronics hauv Asmeskas.

Capacitors: Kuv pom zoo Electrolytic capacitors los ntawm Nichicon, Panasonic thiab Elna Kuv pom zoo polyester thiab polypropylene hom capacitors los ntawm Wima, Epcos, Vishay thiab Panasonic.

Cov Khoom Siv Hluav Taws Xob: 2-Core Copper shielded cable Cov tooj liab tiv thaiv kab no txo kev cuam tshuam thiab txhim kho lub teeb liab zoo

Stereo Volume Control: Siv ALPS Stereo 10K Log Potentiometer

Pin1: Hauv av (Luv 2 Pins thiab Txuas rau GND)

Pin2: Txuas rau Kab-Hauv Amplifier (Sab laug/Txoj Cai)

Pin3: Sab Nraud Tawm Tswv Yim los ntawm RCA Jacks (Sab laug/Txoj Cai)

Kauj Ruam 1: Luam Koj Lub Rooj Tsav Xwm

Kuv siv https://www.oshpark.com rau xaj kuv cov PCBs. Txuas nrog yog PCB *.brd cov ntaub ntawv uas yuav tsum txaus rau kev xaj ntawm Oshpark. 3 cov laug cam yuav raug nqi koj kwv yees li $ 17.50. Lawv ua tau zoo. Kuv tsis pom zoo luam ntawv lawv hauv tsev vim lawv siv 2 txheej thiab ploj ib qho ntawm cov kev sib txuas tuaj yeem ua rau lub hauv paus tsis ua haujlwm. Qhia ntawm no yog 2 Txheej ntawm PCB (Liab - Sab saum toj txheej, Xiav - Txheej hauv qab) nrog Schematic.

Kauj Ruam 2: Pib Sib dhos ntawm Amplifier

Pib Los Ntawm Me Rau Loj. Thawj tus laug lub Amplifier Chip ua raws los ntawm cov khoom me me thiab nce qhov loj me thiab lwm yam.

PCB muaj cov yam ntxwv Polarity thiab tus nqi rau Inductors thiab Capacitors. Yog koj tsis paub tseeb. Zaub ntawm lub rooj sib tham ua ke lub tshuab hluav taws xob sib dhos thiab tau txais cov ntsiab lus.

Kauj Ruam 3: Npaj Amplifier Enclosure

Kos thiab Npaj Qhov Kev Ruaj Ntseg rau pem hauv ntej thiab sab nraub qaum. Sab nraub qaum xav tau tag nrho ntawm 8 qhov drilled nrog ntau qhov sib txawv. 4 qhov rau tus neeg hais lus tso zis. 2 qhov rau RCA Cov Tswv Yim Nkaus, 1 lub qhov rau Hloov Lub Hwj Chim thiab 1 lub qhov rau DC lub zog txuas. Ntxiv cov ko taw roj hmab rau hauv qab ntawm qhov thaiv.

Kauj Ruam 4: Tshem Cov Hluav Taws Xob rau Kev Sib Txuas

Siav cov xov hlau siv cov hlua hlau txuas thiab ntxiv cov dej ntws me me thiab cov laug rau cov xov hlau kom lawv txuas tau zoo.

Kauj Ruam 5: Txuas Cov Hluav Taws Xob rau Cov Tswv Yim thiab Cov Hluav Taws Xob

Txuas cov xov hlau mus rau cov neeg hais lus thiab Kab hauv. Kab Kab Hauv siv tooj liab tiv thaiv kab hlau. Cov Kab Hauv Los ntawm RCA Jacks mus ncaj qha rau Volume Control thiab Center kais ntawm lub ntim tswj mus rau Kab Hauv ntawm Amplifier.

Kauj Ruam 6: Kuaj Kawg

Txheeb xyuas txhua Cov Hluav Taws Xob txuas rau thiab los ntawm Amplifier. Txheeb xyuas Polarity ntawm Lub Hwj Chim (qhia cais ntawm no).

Kauj Ruam 7: Kaw Lub Vaj Huam Sib Luag Pem Hauv Ntej

Kuaj thiab kaw lub vaj huam sib luag pem hauv ntej ntawm Amplifier thiab Txaus siab rau koj qhov kev tsim tshiab.
