In most audio applications, you need to amplify the sound signal coming from the audio output instrument such as a mobile phone jack or a simple microphone so that you can play it over a speaker or any stereo set. You can use simple opamp circuits for this case too but if you need a higher amplification then you would need a high-power amplifier IC like this TDA2030 Audio Amplifier. You can use this simple TDA2030-based Power Supply Audio Amplifier board module to directly connect the input from your instrument to the speaker. It can only be connected to a single output speaker and has an onboard potentiometer to change the volume of the amplified signal. It also has a power indicator to identify the power state of the module.
TDA2030 Audio Amplifier Module Specifications:
- Working voltage:6-12V
- On board 10 k adjustable resistance, can adjust the volume of the amplification
- On the onboard power indicator light
- 18W Power amplifier circuit
- On board TDA2030A Audio amplifier IC
