No analog conversion required. This MEMS microphone doesn't even have analog out, it's purely digital. If you want to avoid the noise with an analog mic system I2S is a small, low-cost MEMS mic with a range of about 50Hz - 15KHz, good for just about all general audio recording, detection and sensing.
You will need micro-controller with I2S peripheral, that can take digital audio data in! That's where this I2S Microphone Breakout comes in. Instead of an analog output, there are three digital pins: Clock, Data, and Left-Right (Word Select) Clock. When connected to your microcontroller/computer, the 'I2S Master' will drive the clock and word-select pins at a high frequency and read out the data from the microphone. It's a 1.6-3.6V max device only, so not for use with 5V logic.
