MAX9814 Auto Gain Control Stable Microphone AmplifierThe MAX9814 module is a microphone amplifier with automatic gain control (AGC). It is a popular choice for applications where the loudness of the audio signal is not predictable, such as voice recognition, noise cancellation, and audio recording. The AGC circuit automatically adjusts the gain of the amplifier to keep the output signal at a constant level, regardless of the input signal level. This helps to prevent clipping and distortion, even when
