Introduction
As we all know, a microphone and speaker are required devices for public speaking engagements and theatrical productions. At certain events, we use microphones to amplify human voices, while at others, speakers just play music from any music player or mobile phone. We incorporate amplifiers in the systems to amplify audio signals from any device. Amplifiers, in other words, amplify low-power electrical audio signals at the output. So, in this tutorial, we’ll learn How To Make Audio Amplifier 12V Using TDA2030.
The IC TDA2030 is the best choice for designing the amplifier circuit. Because it is a low-cost, easy-to-use IC that is suitable for electronic beginners. Various electronic components are used to construct this circuit. This circuit allows you to listen to the sound clearly by turning up the volume.

Audio Amplifier Circuit
Working Explanation
The functioning of this Audio Amplifier 12V Using TDA2030 is actually fairly easy. First, we’ll provide a 12V DC power source. When an audio input device, such as a smartphone or a microphone, is utilized, It then sent the audio input through a 2.2uF coupling capacitor. A coupling capacitor effectively blocks the DC component of the input signal, allowing only AC to get through.
There is a feedback resistor R4 resistor that is linked between pins 2 and 4 to get the gain. This circuit will not function properly if this resistor is not installed correctly.R1 and C2 are connected in series. Pin 3 of the IC is grounded, while pin 2 is used to hold back disturbances in the audio stream.
The output is coming from pin four of an IC. It then sent the amplified output of the amplifier to an audio transducer, such as a loudspeaker.
Applications and Uses
- When we require high power amplification.
- It’s utilized in audio speakers to create a cascading effect.
- Headsets, microphones, speakers, and other audio electrical equipment
- This circuit can set up home theatre systems.
- For the purpose of recording.
