20 Watt Stereo Amplifier Circuit Diagram. Each ic will give you 20 watt output so the output will be 2 20 watt. This is the scheme diagram of 20 watt stereo audio amplifier which use dual ic tda2005 one ic for left channel and the another one for right channel.

For stereo channel you need to build the two same circuits which will amplify the both of audio channels right and left channel. 20w audio amplifier circuit. Following is the schematic diagram of the simple 20 watt amplifier circuit to help building the system.

Each ic will give you 20 watt output so the output will be 2 20 watt.

20w audio amplifier circuit. Stereo audio amplifier circuit diagram. The circuit of audio amplifier using tda7240 ic requires minimum external parts. The ic also has a lot of good features like loud speaker protection short circuit protection low noise thermal shut down low distortion low noise high current capability etc.
