In this instructable you'll learn, how to make a simple audio amplifier with the TDA2822M. The total cost of the components shouldn't cost much (5$ max) and because the circuit is very simple you don't need a PCB, you can make it on a protoboard.

Step 1: Things You'll Need

You'll need a soldering iron, cutters and solder.

From the components you'll need:

  • TDA2822M 1pcs
  • 10k resistor 1pcs
  • 4k7 resistor 2pcs
  • 10nF cap 1pcs
  • 0u1F cap 2pcs
  • 10uF cap 2pcs
  • "bornier" connector 3pcs

Step 2: Assembly

Start by putting a resistors into the board. When you put them in, bend legs for a little, so they'll stay in. Than solder it .Than put the IC in and solder it. That put the capacitors in and solder than. And finally solder the bornier connectors in.

Step 3: Finish

Congrats now you have your mini amplifier. On the left you have power input. I recommend using 3-4V so there won't be much heat dissipation. In the middle there is a speaker output and on the right there is input.

*Note* It isn't my design of a PCB or a circuit

<p>Hello, will this also work for the TDA2822D instead?</p>
<p>Hello, the D stands just for a version in SO8 housing instead of DIP8 as I have used. The functionality is the same, so you can use it :)</p>
<p>Little amps like this are great! Could you add a clear picture of the schematic? </p>
oh thanks for reminding me I forgot to upload the file. Will do it ASAP as I get back my internet connection on a computer
