XENSIV™ MEMS microphones - low self-noise (SNR), wide dynamic range, low distortions, high acoustic overload point
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 XENSIVTM MEMS microphone performance, Infineon’s extensive network of global partners offer customers a comprehensive portfolio of XENSIVTM 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.

Coming soon! Our new XENSIV™ IM73A135 sets a new performance benchmark in MEMS microphones
Infineon’s latest XENSIV™ MEMS microphone IM73A135 sets a new performance benchmark in MEMS microphones. Best-in-class signal to noise ratio (SNR) of 73 dB and a high acoustic overload point of 135 dB SPL enable crystal clear audio pick up. This high dynamic range microphone with a small footprint of 4 x 3 x 1.2 mm3 is based on Infineon’s new Sealed Dual Membrane MEMS technology, which allows for better handling during assembly. The IM73A135 allows designers to reach a level of high audio performance that was previously only achievable by ECMs while at the same time reaping the benefits inherent in MEMS technology.

Features & Benefits
Infineon´s Dual Backplate (DBP) MEMS technology
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.
