ADMP401 MEMS Microphone Breakout Board

Features :

• ADMP401 MEMs Microphone Breakout Board
• One of the key advantages to this breakout and microphone is the bottom ported input, which means the microphone's input can fit flush against the enclosure of your project.
• 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.
