MAX4466 Electret Microphone Module
ItMAX4466 Electret Microphone ModuleIt operates in the frequency range between 20Hz and 20kHz. With the MAX4466 OP-amp on the back, you can increase the signal coming from the microphone to the desired level. With this OP-amp and adjustable resistor on the back, you can increase the input signal by 25 to 125 times. It provides the opportunity to work with 5V and 3.3V sources with an operating voltage of 2.4V - 5.5V. Using 3.3V source for use with Arduino gives better result in terms of signal quality (Arduino 5V output is louder than 3.3V). The output pin of the module is strong enough to power only very small headphones, so it is necessary to use an amplifier for the use of large headphones or to operate the speakers. The output voltage (Vout) is at an offset to be half the input voltage (Vin) in a quiet environment. You may need to use a decoupler depending on where it will be used. It does not need any signal isolation (decoupler) for use with Arduino or a similar microcontroller, just connect the output pin directly.
