Overview:
This tiny breakout board features the ADMP401 MEMs microphone. One of the key advantages to this breakout and microphone is the bottom ported input
This means the microphone's input can fit flush against the enclosure of your project
Plus you will not have to deal with trying to solder the microphone's wacky footprint
The amplifier on the breakout has a gain of 67 and more than meets the bandwidth requirements of the mic
The amplifier's AUD output will float at one half Vcc when no sound is being picked up
The amplifier produces a peak-to-peak output of about 200mV when the microphone is held at arms length and is being talked into at normal conversational volume levels
So the AUD output can easily be connected to the ADC of a micro
