10Pcs GY-MAX4466 Electret Microphone Amplifier MAX4466 Module Adjustable Gain Breakout Board for Beskrivelse

Using the MAX4466, an op-amp specifically designed for amplifier, which has excellent power supply noise rejection, and the board comes with a 20-20KHz electret microphone soldered . the back, we include a small trimmer pot to adjust the gain.
Power supply voltage: +2.4V to +5.5V (can be compatible with for STM, for Raspberry Pi and other development board motherboards); Power supply rejection ratio: 112dB; Common mode rejection ratio: 126dB; AVOL: 125dB (RL = 100kΩ) rail-to-rail output; Quiescent power supply current: Less than 24μA; Gain bandwidth: 600kHz. The output is rail-to-rail so if the sounds gets loud, the output can go to 5Vpp!
Applications: This breakout board is best used for projects such as voice changers, audio recordingmpling, and audio-reactive projects that use FFT.
Note:For the best performance, use the "quietest" supply available ( an for , this would be the 3.3V supply); For audio-reactive projects, we suggest using an FFT driver library which can take the audio input and 'translate' it into frequencies.
The MAX4466 is a micropower operational amplifier optimized for use as a microphone preamplifier. They provide an perfect combination of optimized gain-bandwidth products and supply current, as well as low-voltage operation in super packages.

Material: PCB+metal
Using introduction:
Connect GND to ground, VCC to 2.4-5VDC.
The audio waveform will come out of the OUT pin. The output will have a bias of VCC/2 so when its perfectly quiet,
the voltage will be a steady VCC/2 volts (it is coupled).
1.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.
2.If you're connecting to an audio amplifier that has differential inputs or includes decoupling capacitors, the 100uF
