In this instructables,I will show you how to make 2 watt audio amplifier. It can give a output of 2 watt. 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.

Frank Donald May 1, 0 Comments. Amplifier Circuits. Mini Audio amplifier Circuits comes into play whenever we like to take music wherever we go. These kind of mini audio amplifier will make the music system light and can be moved from one place to another. Also these kind of amplifiers will reduce the cost without compromising the performance of the music system.
This IC operates with 4. The maximum gain of the amplfier is fixed at This amplifier is capable of driving load of 2 to 3W and will suit perfectly to drive a 8 ohm speaker with a supply of 6V. See detailed description about this IC in Datasheet here.
A variable resistor RV1 is used in order to control the volume of the audio signal. The capacitor C1 and C2 was used to filter the supply voltage and can be eliminated if a battery was used. And the output part comes with a simple 8 Ohms 2Watt speaker. Make sure you select appropriate speaker for this mini amplifier since the chip can only drive up to 3Watt with a 6V supply.
If you use high load speakers you may end up smoking the amplifier IC. Notify of. Notify of all new follow-up comments Notify of new replies to all my comments.
TDA7052 2 Watt Audio Amplifier
This circuit is a 1 watt mono amplifier using the TDA from Philips. It is designed to be used as a building block in other projects where a battery powered audio amplifier is required to drive a small speaker. All Rights Reserved. Circuit Description: There are only 5 external components. C1 is the input coupling capacitor, which blocks any DC that might be present on the input. C2 and C3 provide power supply decoupling, and R2 provides adjustable input level.
