TDA2030

This project was an in-depth exploration of analog electronics, focused on designing and implementing a low-power audio amplifier using the TDA2030A IC. The circuit was engineered to take a mobile phone audio input and drive a small 45 Ω speaker, demonstrating practical amplification principles in a compact design.

The challenge centered on biasing, stability, and heat dissipation while ensuring clean audio output at limited power. Careful attention was given to component selection, PCB layout considerations, and understanding the trade-offs between gain, distortion, and efficiency.

This project strengthened my knowledge of power amplifier topologies, analog signal processing, and hardware debugging, while reinforcing the importance of bridging theoretical design with real-world performance.
