This is a small Stereo amplifier 3W + 3W using BA5406-IC. It use 12V power supply as source of this project. and use a few part so easy to build.
This is 2 watts + 2 watts Stereo small LM386 amplifier x3 ICs. It is cheap and easy to builds for BCL amplifier,mobile,MP3 player using 6V battery (AA x 4) [...]
The IC-TDA2009 amplifier circuit on stereo 10W+10W IC is to qualify from the power supply 8-24V, the current maximum of 1-2A. and 24V load 4 ohms [...]
Relatively easy to build up to 30W Amp OTL by TDA2030 transistor is packed into this project.the power dissipation of 20W at 8 ohm or 30W at load 4 ohm
This is a 4 transistor audio amplifier circuit. Which is a 4-transistors complementary push-pull amplifier, that shows the basics of audio amplifier design.
This is an LM386 audio amplifier that can be used with a small 9 volt Battery Operated,Current use as little as 5 milliamps.And amplification up to 500 mW.
This is TDA2822 small stereo power amplifier. People like TDA2822. Me too. Why? Dual Amplifiers in one. With DIP-8 similar for LM368(Mono). Easy uses. Give power watts at 1W + 1W at 4 ohms speakers. It is enough. We are happy Listening in our corner. Relax... Start voltage supply of 1.8V to 15V. The wide a lot. Save energy with only 6mA, Min. The bandwidth expansion rates at 40dB 120kHz. Cheap and easy
