Watch the mini-series: • MEMS microphones
A MEMS microphone is an electro-acoustic transducer housing a sensor (MEMS) and an application-specific integrated circuit (ASIC) in a single package.
The sensor converts variable incoming sound pressure to capacitance variations that the ASIC transforms into analog or digital output. The acoustic wave enters the microphone through a sound inlet in the top or bottom of the package, hence the top or bottom port nomenclature. MEMS microphones target all audio applications where key requirements are small size, high sound quality, reliability, and affordability.
