This tiny breakout board features the ADMP401 MEMS microphone. 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.
