GY-MAX4466 Electret Microphone Amplifier MAX 4466 adjustable

Deskripsi GY-MAX4466 Electret Microphone Amplifier MAX 4466 adjustable MAX4466 1. The circuit board is equipped with a soldered 20-20KHz electret microphone, This amplifier has excellent power supply noise suppression. 2. Items using FFT: such as voice converter, audio recording / sampling and audio response items. 3. A small trim potentiometer to adjust the gain: you can set the gain from 25 times to 125 times. Down to about 200mVpp , ideal for connecting to something that requires #34;line level #34; input without clipping, or up to about 1Vpp, ideal for reading from microcontroller ADCs. 4. The output is rail-to-rail: Therefore, if the sound becomes louder, the output can reach 5Vpp! 5. It is very simple to use: connect GND to ground and connect VCC to 2.4-5VDC. For best performance, use the #34;quietest #34; power supply available (on Arduino, this will be a 3.3V power supply). The audio waveform will be output from the OUT pin. The output will have a DC bias of VCC / 2, so when it is completely quiet, the voltage will be a stable VCC / 2V (DC coupled). If the audio device you use requires AC-coupled audio, place a 100uF capacitor between the output pin and the input of the device. If you are connecting to an audio amplifier with a differential input or including decoupling capacitors, you do not need a 100uF capacitor.
