(Ready Stock) GY-MAX4466 20-20KHz Electret Microphone Amplifier VCC 2.4-5.5V Adjustable Gain Module
VCC 2.4-5.5V Adjustable Gain GY-MAX4466 20-20KHz Electret Microphone Amplifier MAX4466 Adjustable Amplifier Sensor Module
Specification:
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!
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!
For the best performance, use the "quietest" supply available (on an Arduino, this would be the 3.3V
supply). The audio waveform will come out of the OUT pin. The output will have a DC bias of VCC/2 so when
its perfectly quiet, the voltage will be a steady VCC/2 volts (it is DC coupled). If the audio equipment you're
using requires AC coupled audio, place a 100uF capacitor between the output pin and the input of your
device. If you're connecting to an audio amplifier that has differential inputs or includes decoupling
capacitors, the 100uF cap is not requir
