MEMS mic targets voice-control

January 04, 2017 // By Peter Clarke
InvenSense Inc. (San Jose, Calif.) has announced a MEMS microphone with a signal-to-noise ratio (SNR) of 74dB suitable for far field audio applications such as teleconferencing, voice-controlled home and Internet of Things.

The ICS40730 delivers an analog output and comes in a bottom port surface mount package. The analog output can be used by beamforming and audio processing applications. The 40730 improves on the ICS40720, a 70 dB SNR MEMS microphone has been shipping in volume for over two years.


InvenSense claims the ICS40730 is the highest SNR MEMS microphone available. The ICS40730 is now available for sampling and will be in mass production in Q3 2017.
