Persamaan Ic Lm 386 How To Connect Those

Untuk proyek ini, saya menggunakan LM386 audio mini Amplifier, yang biasa digunakan di kalangan penghobi elektronik.

Namun, kenaikan keuntungan lebih lanjut bisa dilakukan secara eksternal.

Keuntungan dapat dikendalikan dengan menempatkan sebuah resistor dan sebuah kapasitor di antaranya.

Rangkaian versi ini menggunakan komponen yang bukan tipe DIP tetapi komponen yang mudah didapatkan dipasaran.

Potensiometer digunakan untuk mengatur jumlah sinyal input yang akan diperkuat.

Kapasitor kopling digunakan untuk memblokir sinyal DC dan melewati sinyal AC.

Dalam skematik di atas, kapasitor 10uF digunakan antara sumber input ke potensiometer untuk memasangkan sinyal audio.

Saya akan coba jabarkan artikel - artikel yang saya posting dengan mudah dan dapat dipratekan dengan mudah.

Remote XY lets you create graphical interfaces for smartphones.

The IC is designed to deliver a voltage amplification of 20 without external add-on parts.

But this voltage gain can be raised up to 200 (Vu 200) by adding external parts.

The circuit C is not for voltage amplification but will raise the bass level by about 5 dB.

Take note that the circuit C is to be connected between pins 1 and 5 of the IC.

This audio frequency amplifier is ideal for small battery powered devices.

If you use the external circuit A, replace the Rx with a jumper wire in the PCB.

If you use the external circuit C, solder the additional resistor and capacitor to the PCB points labeled Rt and Cy.

In case of external mic signal, it needs to preamplify first then fed to lm386 ckt.

Most microphone signals are too weak for LM386 on its own and require the signal to go through a preamp stage.

I am unclear however how you intend to pass the microphone signal from your mobile phone and whether the phone has a microphone output which is already pre-amplified.

Can you give me an explanation how to connect those 3 wires or schematic diagram will do.
