MAX9812L Amplified Microphone for Measuring Sound The MAX9812 is a sound amplifier specially designed to treat the signal coming from microphones.We can use it together with Arduino to measure sound from a processor like Arduino.When we saw the modules with microphone we commented that, in general, the signal generated is too low to be registered correctly.If we want to be able to measure sounds, we will have to amplify the signal. The MAX9812L has single / dual inputs, fixed gain of 20dB, bandwidth of 400 kHz, low noise and low signal distortion 0.015% THD.There are two models, its supply voltage is 2.7V to 3.6V.We can use the sensors with MAX9812 for applications that require measuring the intensity or frequency of the sound.
