Q & A

The MAX9814 Electret Microphone Amplifier with Adjustable Gain Module is best used for projects involving voice change decibels (dB), audio recording/sampling, and audio-reactive projects that use FFT.

The MAX9814 offers various configuration options to adjust gain and attack/release ratio, allowing for flexibility in different audio setups.

The default gain of 60dB can be Adjusted to 40dB or 50dB by connecting the Gain pin to VCC or ground. The attack/release ratio can also be modified from the default 1:4000 to 1:2000 or 1:500.

With a maximum output of about 2Vpp on a 1.25V DC bias, the amplifier is compatible with Analog/Digital converters with up to 3.3V input. A 1-100uF blocking capacitor in series can be used to connect it to a Line Input.

This setup allows versatile integration into various audio systems while ensuring compatibility and quality output.
