20 Watt Power Amplifier

[ElectroMaster]

This IC chip was designed specifically for use in power boosting applications in automobiles. It is self protecting against short circuits and thermal problems.In the bridge configuration shown it will deliver 20 watts of power into a 2 ohm speaker operating at 14.4 volts.

is there a way to step up the output, i would like to get it to around 250 watts

 

[Platonas]

No way.
Build a larger more complicated circuit for the 250W.

hey dude could u tell me about making an amplifier for my car subwoofer..im in urgent need for this.

 

[Dr.EM]

For a sub you'll need a lot of power and it'll almost certainly be cheaper to buy a ready made one.

triangles

i believe these triangular shapes r the operational amplifiers,correct me if i m wrong.

Sort of?, they are POWER operational amplifiers, but specifically intended for audio use.

no way!!!

you cant get any more power on that IC

its characteristic is the same as LM2005T

20 watts bridge connection

for a 250 watts, you can only attain this power by using higher supply voltage such as +/-35 volts

Oh I think we can squeeze 250 watts out of that circuit.... say IHF ratings at 1kc. for 1 microsecond.

hi there!!!!

hi

i think i can make this 20 watts to give around 100 - 200 watts output...

if your interester mail me: game_master_287@yahoo.com

URGENT o I use it for 5 watt RMS Power Amp

can I use this circuit for 5 watt RMS Power audio Amplifier with low distortion.....if yes plz reply the require changes.....it's urgent for me....

plz

urgently

The TDA2005 isn't a hi-fi amp, it is a car radio amp. Its distortion is typically 0.3% (1% max) as a 2-channel stereo amp, up to 6W RMS per channel into 2 ohm speakers and a 14.4V supply.
If you want very low distortion then use a hi-fi amp IC. They need a supply voltage much higher than a car battery and drive 8 ohm speakers.

thanks buddy ....for this suggestion...i have made the correct ckt diagram....

 

[legrotalia]

ooooooooooooooooooooo....

 

[Hero999]

Baaaaaaaaaaaaaaaaaaaaaaaaaaaaaa......

 

[jfire]

hello guys i need a 200 watt audio amplifier for my major project,
i need a stable and working ckt which looks a big project plz try to help me

 

[Nigel Goodwin]

Well copying someone elses work probably isn't going to get you much of a mark?. But try here! https://www.ampslab.com/projects.htm

 

[palesha]

Here is the list of ic's. little old but ok.
Now new development r class D based & not suitable for newbies.

 

[audioguru]

How far would I need to drive to buy old low power Russian amplifier ICs?? About 20,000km?

High End Audio Amplifier

Is there anyone interest with creating new Hi-End Audio Amplifier thread?
I've initiate it, but I've no access to do it.

I'll help to start it with my 7th version K32 that been fixed in dec2005.
And also analyze old halcro schematic.
