Introduction: TDA7052 2 Watt Audio Amplifier
In this instructables,I will show you how to make 2 watt audio amplifier.It can give a output of 2 watt. The heart of this circuit is the IC TDA7052. It is a IC with 8 pins. This circuit can be operated with only 6 Volt.This is the easiest mono amp which uses less parts.I hope you would like it.

Step 1: Things You Will Need
The things you will need are:
1. 1 TDA7052 IC: You’ll find this IC online and
electronic stores. About this IC.
2.2 capacitors of 220µF of any volt, 100nF ceramic
capacitor (you don’t need the capacitors if you’re using batteries).
3.A 4.7 k volume control (potentiometer) and,.
4.1 inch x 1 inch Vero board: You can use Perf board,
5. Some Wires.
7. 3.5 mm headphone jack.
Step 2: Making the Circuit
Here is the circuit of the amplifier.I made it on a Vero board and soldered it.If you don’t know how to solder then visit this page.I used the 8 pin base(socket) for safety of my IC. In the picture you see I cut the connection between the IC’s pins. In the picture I didn’t use the capacitor because I used batteries, but if you want to adapter then use the capacitors. I taped those wires in the picture with the Vero board for easiness. This circuit will give an output of 1 to 2 watt.If you try this circuit on a breadboard (Project board) maybe it won’t work well. But if you solder it on Vero board or perfboard it will work great.
Step 3: Tasting the Circuit
Connect the jack to your iPod, mp3 or mobile phone and play audio. I hope it will work great.
