5W Stereo Amplifier For Noise Free Music | Best Electronics Project


Hey freaks, Welcome again to Freaky Diodes. We are back with another awesome electronics project. In this project, we have made a 5W Stereo Amplifier For Noise Free Music. It is a very simple and easy project. This simple 5W stereo audio amplifier is based on an IC TA8207K of 12-pin and requires a couple of few resistors, electrolytic & ceramic capacitors. The output power of about 4.6W for the left and right channels is given using a 12V DC supply.

Working & of Stereo Amplifier :

As shown in the circuit diagram the connections of Stereo Amplifier are as follows:

  • The 3rd & 12th pins of TA8207K IC1 are connected to the positive terminal of the battery.
  • The 6th & 7th pins of the IC are used for inputs of left & right audio.
  • A pot of 100-kilo-ohm can be connected for volume control for each input of the amplifier.
  • The LS1 & LS2 are the loudspeakers connected to pins 2 & 10 of IC1 through electrolytic capacitors C8 & C9.
  • The C10 electrolytic capacitor is connected between +12V and ground. It works as a noise filter.

  • This amplifier can be implemented on a 5cm×6.5cm Veroboard, or on the PCB whose layout is given.
  • The TA8207K IC can be vertically inserted into the Veroboard or PCB.
  • Assemble the circuit and connect the audio input from the source, across CON2 and the LS1 & LS2 two speakers.
  • Now, connect the 12V battery across CON1.

Connect the two speakers and 12V battery to the amplifier. Touch it gently with the screwdriver on any of the inputs at the 3-pin connector (CON2), a humming sound coming from the speakers.

Now, connect the audio output of source of signal to CON2 and we get the noise-free amplified music.
