The MAX4466 Electret Microphone Amplifier with Adjustable Gain Module is best suited for voice changes, audio recording/sampling, and audio-reactive projects utilizing FFT. The amplifier utilizes the Maxim MAX4466 op-amp, providing excellent power supply noise rejection for high-quality sound output.
The module includes a small trimmer pot on the back for adjusting the gain from 25x to 125x, allowing for versatile usage scenarios. With an output range from 200mVpp to 1Vpp, it can be connected to various audio devices without clipping.
For usage, connect GND to ground and VCC to 2.4-5VDC. The audio waveform is output through the OUT pin, with a DC bias of VCC/2 for quiet moments. A 100uF capacitor can be added for AC-coupled audio requirements.
Package Includes: 1 x MAX4466 Electret Microphone Amplifier with Adjustable Gain Module, 1 x Header Set (Without Soldered).
