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.
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 [...]
This is small integrated amplifier at 20W using a TDA2004 or TDA2005 IC,use 12V supply for BCL car audio amps[...]
SEE! Many Power amplifier circuit diagram with PCB layout. So easy to builds. You can choose 0.5W to 1,200W. Using transistors, MOSFET, IC on a lot types
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
The Mini stereo tone control circuit with IC, circuit diagram use just IC-TDA1524A and a few parts, It adjust Volume, Balance, Bass, Treble in small circuit
This is a car audio amplifier circuit that has high power over than 50w Using the IC TDA1562Q Philips. Which It uses just 12 volts power supply only.
