This guide shows how to connect the Adafruit Electret Microphone Amplifier to measure sound levels with your Arduino.  
  
The Microphone Amplifier mates an [Electret Capsule Microphone](http://www.adafruit.com/datasheets/CMA-4544PF-W.pdf) with a [MAX4466 Operational Amplifier](http://www.adafruit.com/datasheets/MAX4465-MAX4469.pdf) optimized for use in microphone pre-amplifier applications.  The flexible supply voltage and and adjustable gain make this module adaptable to a wide variety of audio applications.

## Specifications:

- Supply Voltage: 2.4v-5v  
- Output: Rail-to-Rail - up to to 5vp-p  
- Frequency Response: 20Hz - 20 KHz  
- Adjustable Gain 25x-125x  
- [Available From:  Adafruit of course!](http://www.adafruit.com/products/1063 "Link: http://www.adafruit.com/products/1063")
