Description:
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. For the amplification, we use the
Maxim MAX4466, an op-amp specifically designed for this delicate task! The amplifier has excellent power
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!
This breakout is best used for projects such as voice changers, audio recordingmpling, and audio-reactive projects that use FFT. On the back, we include a small trimmer pot to adjust the gain. You can
set the gain from 25x to 125x. That's down to be about 200mVpp (for normal speaking volume about 6"
away) which is good for attaching to something that expects 'line level' input without clipping, or up to
about 1Vpp, ideal 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!
