Digital Output I2S MEMS Microphone - SPH0645LM4H lead screw All input signals are isolatedNo 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
