MEMS Microphone Devices

Overview

InvenSense’s analog and digital microphone portfolios build on a strong heritage of industry firsts, including continuous improvement of MEMS microphone SNR, ever-higher integration levels, and even lower power consumption. Technological advances like these have enabled machine speech recognition & active noise cancellation to become commonplace in consumer devices and other applications.

Humans intuitively understand audio capture to be a critical factor in awareness of their surroundings. InvenSense is working to enable the same level of awareness for smart devices with leading-edge MEMS microphones. InvenSense combines the capability to sense audio along with cutting-edge motion detection, which is important for many contextual awareness applications.

InvenSense microphones are listed in the table below.
