Audio Amplifier Circuit Diagram

[Andrew Russel]

Hi,


I have been looking for a decent stereo amplifier circuit diagram for quite a while. I am not a HiFi nerd, I simply needed to fabricate a straightforward stereo amplifier that could drive a few speakers for my desktop PC.


All the schematic graphs that I could discover appeared to include heaps of elusive parts or you needed to utilize it together with a pre-amplifier or some other amplifier arrange. It was continually something that influenced me to delay.







But recently I found this wonderful little chip called TEA2025B. We just need a couple of capacitors to influence a better than average stereo speaker to out of it. It is so easy to construct that I set up it together on a stripboard in only a couple of hours.


The amplifier circuit diagram demonstrates a 2.5W * 2 stereo amplifier. We can likewise make a 5W mono amplifier out of it. There are numerous potential outcomes when you can influence such to a modest amplifier.

Thanks for any advice.

Looks like it'll get the job done.

Here's another option....

At the TV station where I work part time, we used a bunch of these kits, along with some small full-range TV speakers like these....

The assembled board and speakers fit nicely on the back of a single-RU vent panel, and you've got a rack-mountable stereo loudspeaker for PC's, TV's, etc. I just had to add a small pigtail cable with a stereo mini jack to the amp board for plugging stuff in.
