I'm building an audio amplifier. These are the project requirements:
- Type of Amplifier: Class D (for energy efficiency).
- Input Source: Line-level input from a standard audio source, e.g., mobile phone or PC.
- Output Power: 10W per channel (for a stereo setup).
- Number of Channels: 2 (stereo output).
- Distortion: Total Harmonic Distortion (THD) of less than 0.1% at full power.
- Frequency Response: 20Hz to 20kHz.
- Power Supply: Operate from a single 12V DC source.
- Protection: Over-current and thermal protection for the amplifier IC.
- Connectivity: Standard 3.5mm audio jack for input and screw terminals for speaker outputs.
- Volume Control: A physical potentiometer for volume control.
- Indicator: An LED indicator that shows power ON status.
- Size Constraints: PCB size should not exceed 100mm x 100mm.
