Overview:
If you are building a sound sensor for your microcontroller, chances are you settle on a LM386-based microphone amplifier. It’s cheap, readily available and doesn’t require too many external parts.
- Minimum external parts
- Wide supply voltage range: 4V–12V or 5V–18V
- Low quiescent current drain: 4mA
- Voltage gains from 20 to 200
- Ground referenced input
- Self-centering output quiescent voltage.
- MIC Connection.
- Speaker Connection.
- High quality PCB FR4 Grade with FPT Certified.
