Micrófono MEMS

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.
