Continuous innovation on various technology nodes has been the key enabler of new, innovative and advanced audio features for consumer electronics. Novel functionalities such as Active Noise Cancellation (ANC), transparent hearing, AI-assisted voice control or audio-zoom are just the beginning of an ongoing audio revolution driven by advances in audio processing algorithms, microelectronics and microelectromechanical systems (MEMS) sensors.

Infineon XENSIV™ MEMS microphones are at the forefront of this revolution by capturing audio signals with unprecedented detail and hence providing the best possible input for the audio signal processing chain. Our MEMS microphones feature ultra-low self-noise (high SNR), extremely low distortions (THD) even at high sound pressure level (SPL), very tight phase and sensitivity matching, a flat frequency response with a low LFRO (low frequency roll-off) and ultra-low group delay. Combined with selectable energy efficiency modes and their very small package size, Infineon XENSIV™ MEMS microphones are the perfect match for all portable consumer devices.

Navigate the “hearing”, “communication” and “recording” use-cases and browse through our product specs below to find the ideal match for your use case and to learn more about how XENSIV™ MEMS microphones can enable your device for the next generation of advanced audio features.

Brilliant hearing with XENSIV™ MEMS microphones

lorem ipsum

lorem ipsum

Differentiate your TWS hearable, headphone or headset device with Infineon’s XENSIV™ MEMS microphone to give your customers the best possible listening experience. An ultra-high SNR, a very low LFRO (low frequency roll-off), ultra-low latency and a very high acoustic overload point (AOP) enable best-in-class active noise cancellation and transparent hearing functionality under all conditions.

Binaural listening experience with Infineon MEMS microphones

Immerse yourself in a virtual sound stage! A human auditory system is simulated by placing two Infineon high performance MEMS microphones in the ears of an artificial head. These are connected to an Infineon Audiohub Nano board that sends the recorded sound directly to your headphone. Because of the low self-noise of the microphones, it feels like you are listening with your own ears and are right were the action is!

 

Noise-free communication with our XENSIV™ MEMS microphones

lorem ipsum
lorem ipsum

Ultra-low self-noise, very high AOP and very tight phase and sensitivity matching makes Infineon’s XENSIV™ MEMS microphones especially suited for high-quality audio communication in all environments. Improve the phone call and online-meeting experience of your customers by capturing crystal clear, noise-free audio and by combining multiple microphones in an array and thus selecting only relevant audio sources with beamforming and source separation techniques in your smart phone, hearable, laptop or conference speaker products.

High-quality recording with our XENSIV™ MEMS microphones

Transform your smart phone, camera, headset or smart speaker into a state-of-the-art recording device by implementing Infineon’s XENSIV™ MEMS microphones. Our ultra-low noise microphones enable reliable voice pickup at maximum range for AI-assisted voice control units and the very tight phase and sensitivity matching of our parts enable advanced beamforming techniques for multi-user voice pickup and audio zoom features.

 

Experience high performance Infineon XENSIV™ MEMS microphone

What is the difference between a high and a low performance MEMS microphone? Hear for yourself! In this demonstrator, we focus on a microphone’s dynamic range, which describes how well microphones can record quiet as well as very loud sounds. The upper limit of a microphone’s dynamic range is defined as the Acoustic Overload Point (AOP) - the maximum volume a signal can have before the physical limits of the microphone are reached. The lower limit is defined by the microphone’s self-noise level, or Signal to Noise ratio (SNR). A microphone can only record sounds above its self-noise level. Here, you will get to hear how recordings sound differently based on whether you use a low or a high dynamic range microphone.
