MEMS Microphones

The popularity of voice user interfaces and the usage of audio recording to share information and experiences are increasing dramatically. However, the performance of microphones often limits the potential of today’s cutting-edge devices. Not anymore!

Infineon XENSIV™ MEMS microphones introduce a new performance class for MEMS microphones that overcomes existing audio chain limitations. IM69D130 is designed for applications where low self-noise (high SNR), wide dynamic range, low distortions and a high acoustic overload point are required. Infineon’s latest analog XENSIV™ MEMS microphone IM73A135 pushes the level of audio performance even further.

Building upon the superior XENSIV^TM MEMS microphone performance, Infineon’s extensive network of global partners offer customers a comprehensive portfolio of XENSIV^TM MEMS microphone-based reference designs, as well as Infineon inside MEMS microphones that will propel audio performance to the next level even for the most demanding applications.

Infineon's dual backplate MEMS technology is based on a miniaturized symmetrical microphone design, similar as utilized in studio condenser microphones, and results in high linearity of the output signal within a dynamic range of 105 dB.

The microphone noise floor is at 25 dB[A] (69 dB[A] SNR) and distortion does not exceed 1 percent even at sound pressure levels of 128 dB SPL (AOP 130 dB SPL). The flat frequency response (28 Hz low-frequency roll-off) and tight manufacturing tolerance result in close phase matching of the microphones, which is important for multi-microphone (array) applications.

Our Infineon inside MEMS microphone partners provide you with a full range of MEMS microphones suitable for a variety of applications.
