If you would like to build a HI-FI power amplifier project that power output size about 30 watts to 50 watts or 75 watts at 8 ohms loudspeaker, and is high-quality sound and easy to build not too many components. Below that builds with the integrated circuit, PCB layout and no need for any customization. Parts used in this circuit are easily available in most of the local markets. Moreover, the TDA delivers typically 50W.

It commonly used in class-AB audio amplifier and can drive upto 50W music power into a 4 ohm speaker. TDA is a general-purpose 32W amplifier IC that can be used in stereo or mono audio design circuits. The amplifier can output upto 5A current to drive speakers without any damage. It can also handle short circuits in both AC and DC rail without killing itself.
This makes it robust to be used in automotive audio designs. The TDA is breadboard friendly and hence can be easily tested using a breadboard. A sample application circuit for TDA is given below. The tda datasheet given at the bottom of this page consists of more details on this design. The pin 5 and 3 are used to power the Amplifier IC, and the audio signal to be amplified is given in through pin 1 which is the non-inverting input.
The amplified audio output can be obtained through pin 4. The values of the components given above are the values recommended by manufactures. Note that this IC has currently become obsolete and is no longer in production, though you can find few clones being sold in the market by different manufacturers.
