3 Watts Audio Amplifier || DIY Mini Power Amp! || IC 8002

This video is about making a small but powerful DIY audio amplifier using IC 8002 which is a 3 watt power amplifier capable of driving pretty powerful speaker. You can also power it from a Lithium Ion battery making it portable.

Thanks bro i've tried with 8002D ic and it sounds incredible i subscribed you

Thanks man!

Sir are you in kolkata

Hello !
¿What is the diference in 8002A and 8002B? Thanks.

[@pentagono9192]

Great joob name of song

[@yamuhatph2530]

sir what it that equipment used in pcb layout?

[@UtsavShah_25]

I've used a cnc engraver for the PCB design fabrication

[@jokolewung9093]

is it save to connect to phone for audio source?

[@UtsavShah_25]

Yes it is totally safe to connect to a phone

[@aernancoc]

can you use 101 caps?

[@UtsavShah_25]

I assume you mean 100pf capacitor. In that case the frequency response can be different

[@rohitshukla4923]

Where is the left audio jack wire would be connected. It is not shown in PCB nor in diagram?

[@UtsavShah_25]

This is a mono or a single channel amplifier so only one channel can be amplified. For stereo amplification 2 such ICs are needed

[@rohitshukla4923]

@@UtsavShah_25 ok lot of thanks Utsav. It means in one IC volume would be lower or not properly give the sound as only one audio Jack is connected. Please correct if i am wrong.

[@UtsavShah_25]

@@rohitshukla4923 for only one speaker you can connect both left and right channel audio together and feed it

[@roglopes.mobile2568]

Does this amplifier support 2 speakers 4ohms?

[@UtsavShah_25]

I am assuming that you will put those 2 speakers in parallel which will make the impedance at 2ohms. It may work but sound quality will get compromised

[@roglopes.mobile2568]

@@UtsavShah_25 but if I use them in serie mode and get 8 ohms. Will work?

[@UtsavShah_25]

@@roglopes.mobile2568 I guess it will work but I'm not sure how the sound quality will turn out to be..even I need to try it

[@rohitshukla4923]

@@UtsavShah_25 if we use 8ohm , then it can burn IC or speaker ?

Junk ic..so bad audio. Make bd139 amp.. Real amp in 3watt
