## Overview

The NOYITO MAX4466 Electret Microphone Amplifier is a compact, pre-assembled audio module featuring a high-fidelity MAX4466 op-amp and a built-in electret microphone. It offers adjustable gain from 25x to 125x via a trimmer pot, supports a wide frequency response of 20Hz to 20kHz, and operates on a low-noise 2.4-5V power supply, making it perfect for Arduino-based voice changers, audio sampling, and FFT projects.

## Description

NOYITO MAX4466 Electret Microphone Amplifier Adjustable Gain (Pack of 2)

## Features

- Add an ear to your project with this well-designed electret microphone amplifier. This fully assembled and tested board comes with a 20-20KHz electret microphone soldered on.
- For the amplification, we use the MAX4466, an op-amp specifically designed for this delicate task! The amplifier has excellent power supply noise rejection, so this amplifier sounds really good and isn't nearly as noisy or scratchy as other mic amp breakouts we've tried!
- This breakout is best used for projects such as voice changers, audio recording/sampling, and audio-reactive projects that use FFT.
- On the back, we include a small trimmer pot to adjust the gain. You can set the gain from 25x to 125x. That's down to be about 200mVpp (for normal speaking volume about 6" away) which is good for attaching to something that expects 'line level' input without clipping, or up to about 1Vpp, ideal for reading from a microcontroller ADC. The output is rail-to-rail so if the sounds gets loud, the output can go up to 5Vpp!
- Connect GND to ground, VCC to 2.4-5VDC. For the best performance, use the "quietest" supply available (on an Arduino, this would be the 3.3V supply). The audio waveform will come out of the OUT pin. The output will have a DC bias of VCC/2 so when its perfectly quiet, the voltage will be a steady VCC/2 volts (it is DC coupled).
