How to make a simple amplifier (TDA7052A chip amp)

[@parthabhatta1963]

Very clearly explained. Thanks. 👍

[@ranman58635]

Easy to understand. I've been trying to learn for some time now. Ty

[@rexacosta70]

Sir. Like your explanation

[@chalcool740]

thanks for the video. question. why didnt you use the 100nF capacitor ? thanks

[@neppynep1453]

Great video with lots of information. If I was to design a tda7052a amplifier circuit with a transistor switching circuit to trigger a mute function, how would u change the circuit?

[@LeftyMaker]

The chip goes into mute if you connect pin 4 to ground

Thanks for the support!

thanks a lot for this video. please make more of such videos

[@LeftyMaker]

You're welcome. Anything in particular you want to learn about?

@@LeftyMaker I want to learn how to make my own mic at home. An amplifier which will provide a bandwidth which removes all the bad noise while boosting my voice so it can be clearly recorded into the desktop using TRS 3.5mm jack. it would also be great if the mic is not required to stay close to my mouth and I am allowed to place it anywhere near me like of the table. ( I would like to completely eliminate the background noise and provide loud and crisp voice just from the 3.5mm jack and not from added power source like a battery). It would be great if the mic is made with lower cost in mind. The main component should be the electret mic. If this is possible I would be very happy and would surely suggest the video to all my friends studying electrical engineering with me. Thanks a lot for giving me a chance to share my idea with you!

One more thing when you are showing the parts you choose can you also explain why did you choose them? like with calculations if possible.

[@LeftyMaker]

@@dutch759 DIY Perks did something similar already. What you are describing is a shotgun microphone. www.instructables.com/DIY-Shotgun-Microphone-with-wind-shield-in-buil/

[@dutch759]

@@LeftyMaker so you are not interested to make your own for the channel? I wanted to learn from you cause I like the way you teach.

I am trying to drive a 2.5 watt speaker,, using this chip. will it be okay, if i tried this, trying to make an amp fo a disk cutter, i read up on some specs i liked of this chip..I just want to drive the speaker,,

[@chrisg0001]

This is excellent. Could you do something around 5watts for a guitar amplifier?

[@LeftyMaker]

Hm, I've never tried making one. I don't have a guitar 🙃 You can try searching for the Ruby amp or Little Gem amp and see if that works for you.

[@chrisg0001]

@@LeftyMaker what makes a normal line amplifier different from an instrument amplifier. I saw that they use a transistor of some sort, but I am unfamiliar with the application

[@LeftyMaker]

@@chrisg0001 I think a J-FET is used for impedance matching and pre-amplification purposes.

[@mrbk1120]

Minimum and maximum voltage needed???

[@LeftyMaker]

Go with 6V. Anything below that and you won't get full power. Anything above that will cause the chip to get warmer.

[@RaulMarta4]

Can i use other capacitor instead 0.47uf?

[@LeftyMaker]

A slightly bigger cap may also work

[@abdullahal-qadi3644]

What is the usage of 470uF on the top ? 6:55

[@LeftyMaker]

It is called a decoupling capacitor.

[@vladimirr.5637]

Это можно сделать с tda7052 ? This is russian language

[@LeftyMaker]

Да, можно, но без DC volume control (пин 4). Поискайте tda7052 datasheet, там схема есть

Thank you for sharing, this is useful! I was recently in a similar situation, where I needed an audio amplifier to drive an 8 Ohm speaker. I ended up making a single-transistor common emitter amplifier. If you're interested, you can check it out here and let me know what you think! kzbin.info/www/bejne/h3isn6qHlsSLe68
