Fuhjythy -MAX4466 Electret Microphone Amplifier Sensor with Adjustable Gain

For the amplification, we use the MAX4466, an op-amp specifically designed for this delicate task! The amplifier has supply noise rejection, so this amplifier sounds really good and isn't nearly as noisy or scratchy as other mic amp breakouts we've tried! On the back, we include a small trimmer pot to adjust the gain. You can set the gain from 25x to 125x. Add an ear to your project with this well-designed electret microphone amplifier. This fully assembled and tested board comes with a 20-20KHz electret microphone soldered on. This breakout is best used for projects such as voice changers, audio recording/sampling, and audio-reactive projects that use . That's down to be about 200mVpp (for normal speaking volume about 6 inch away) which is good for attaching to something that expects 'line level' input without clipping, or up to about 1Vpp, Perfect for reading from a microcontroller ADC. The output is rail-to-rail so if the sounds gets loud, the output can go up to 5Vpp!
