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 & adaptive noise suppression 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.

Our next generation of InvenSense microphones fit in all mobile applications where low power, high fidelity, tight sensitivity matching and high acoustic overload point (AOP) are important.  

Multi-mode microphones are ideal in ‘AlwaysOn’ applications where the current consumption is significantly reduced in Low-Power mode. InvenSense is the only company offering a high SNR and AOP multi-mode solution for both analog (ICS-40618/40619) and digital (ICS-41350) microphones.

High SNR is beneficial ensuring voice or music is picked up with high fidelity over larger distances, crucial in speakerphones and conferencing systems. The ICS-40720 is offered with industry-leading 70 dBA SNR.

Matching top and bottom port microphones in the 65 dBA SNR class allow a high degree of freedom in packaging mobile devices. The ICS-40180 and ICS-40181 are designed specifically for mobile devices such as smart phones.
