The MAX9814 Microphone Amplifier Module is a high-performance audio amplifier designed to provide clear and amplified audio signals from microphones. Featuring built-in Auto Gain Control (AGC), this module automatically adjusts the amplification level based on the input signal, ensuring consistent audio output and minimizing distortion.

Key features:

  • Auto Gain Control (AGC): Automatically adjusts the gain of the amplifier based on the input signal level. This feature helps maintain consistent audio levels and reduces distortion, making it ideal for applications with varying sound intensities.
  • Low Noise: Designed to provide high-quality audio amplification with minimal noise and interference, ensuring clear and accurate sound reproduction.
  • High Sensitivity: Capable of amplifying weak audio signals from microphones, making it suitable for a range of audio applications.
  • Adjustable Gain: Offers an adjustable gain setting via a potentiometer, allowing for fine-tuning of the amplification level to match specific project requirements.
  • Easy Integration: Features a simple 3-pin interface for connection to microphones and other audio sources, and can be easily integrated with microcontrollers and audio processing systems.
