Electret Microphone Amplifier Stable MAX9814 Auto Gain Control for

Electret Microphone Amplifier Stable MAX9814 Auto Gain Control for Arduino Fetures : Add an ear to your project with this well-designed electret microphone amplifier with AGC. This fully assembled and tested board comes with a 20-20KHz electret microphone soldered on. For the amplification, we use the Maxim MAX9814, a specialty chip that is designed for amplifying electret microphones in situations where the loudness of the audio isn #39;t predictable. This fancy microphone amplifier module is a step above the rest, with built in automatic gain control. The AGC in the amplifier means that nearby #39;loud #39; sounds will be quieted so they don #39;t overwhelm amp; #39;clip #39; the amplifier, and even quiet, far-away sounds will be amplified. This amplifier is great for when you want to record or detect audio in a setting where levels change and you don #39;t want to have to tweak the amplifier gain all the time.
