Adafruit Electret Microphone Amplifier – MAX4466 with Adjustable Gain

Looking for Max4466 Amplifier? Adafruit Electret Microphone Amplifier – MAX4466 with Adjustable Gain is available at Zbotic with fast shipping across India.

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 Maxim 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 get loud, the output can go up to 5Vpp!

Features:

1. Adjustable gain
2. You can set the gain from 25x to 125x
3. Excellent power supply noise rejection

Package Includes:

1 x Adafruit Electret Microphone Amplifier – MAX4466 with Adjustable Gain

Frequently Asked Questions

Can I connect the MAX4466 amplifier directly to an Arduino analog pin?

Yes. Wire VCC to your Arduino’s 5 V (or 3.3 V), GND to ground, and OUT to any analog input pin. Use analogRead() to sample the amplified audio signal for processing or visualization.

How do I adjust the amplification level?

The small trimmer pot on the back of the board sets the gain. Turn it clockwise for higher gain (up to 125×) or counterclockwise for lower gain (down to 25×), while monitoring the output to avoid distortion.

What frequency range does this microphone amplifier support?

The built-in electret microphone and MAX4466 op-amp combination capture audio across 20 Hz to 20 kHz, making it suitable for voice recording, music analysis, and general sound detection.
