TDA2050 Ses güç amplifikatörü

[guclusat]

This project is an audio amplifier based on TDA2050 and LM1875.

Description
This is not an ordinary project, but an attempt to make a PCB that is suitable for TDA2050 andLM1875 and has all the necessary circuitry on board – power supply, speaker protection, delayed turn-on and fast turn-off. This is achieved using the convenient uPC1237 IC.

TDA2050 and LM1875 are pin to pin compatible, the differences in their schematics are the values of a couple resistors and one capacitor. All this allows to make an universal circuit board, suitable for any of these two ICs.

It is 2x30W, but it depend of the power supply voltage and the impedance of the speakers connected to the output.

TDA2050

mungkin ada yang mau merakit ampli mini buat dikamar atau sound komputer? mungkin Chip-Amp yang satu ini bisa jadi pilihan. selain harganya yang sangat terjangkau juga suara yang dihasilkan bisa memanjakan kuping kita. yah kata orang-orang Chip-Amp satu ini adalah saingan LM1875 (meskipun masih bagusanLM1875) . ini skemanya…



Skema TDA2050



layout TDA2050


Biaya merakitnya juga gak mahal, sekitar 20-25rb sudah jadi (kecuali kalau pakai part super ya….) dan cocok buat pemula yang lagi belajar rakit ampli. ini contoh yang sudah jadi tinggal masuk
kandang pakai part seadanya.



daya sekitar 30watt dengan vcc 18vac 2-3 Amper cukuplah buat speaker 4″-6″ . meskipun kecil suaranya ajiibb….
