Meillre, E. com This microphone doesn't even have analog out, its purely digital. The output of the microphone is a PDM signal. An exotic new microphone has arrived in the Adafruit shop, a PDM MEMS Microphone! PDM is the ‘third’ kind of microphone you can integrate with electronics, apart from analog or I2S. We've added a digital MEMS microphone for folks wanting to experiment with always-on voice commands with TensorFlow and machine learning. Requires 5V in. The MEMs microphone comes with a transducer element which converts the sound pressure into electric signals. Kussener, H. The sound pressure reaches the transducer through a hole drilled in the package and the transducer’s signal is sent to an ADC which provides with a signal which can be pulse density modulated (PDM) or in I2S format.
