ماژول میکروفون دارای پری آمپلی فایر MAX4466

MAX4466 is an amplifier module based on the MAX4466 chip that amplifies the output of the microphone and improves the quality of the output sound by removing the noise of the power supply. The frequency of this module is 20 Hz to 20 kHz.
To change the gain of the microphone, you can use the built-in potentiometer behind it.
This gain can be changed from 25 times to 125 times.
Also, by increasing the volume, its output increases up to 5Vpp.
The minimum audio output voltage should be about 200mVpp, otherwise it can be recognized that the line is disconnected.
