    Copilot v4 DogFooding - Audio Amplifier

    Copilot v4 DogFooding - Audio Amplifier thumbnail
    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.
    Consider every requirement individually when answering any question
