XENSIV™ MEMS microphones
As automatic speech recognition systems and the sharing of information and experiences through video content become ever more popular, greater importance is being placed on the performance and quality of the microphones used in audio capture devices. Key performance criteria for satisfactory user experience include noise distortion, and frequency response. Infineon’s latest XENSIV™ MEMS microphone IMD69D, meets these requirements, providing high performance audio recording in speech recognition and audio/video capturing systems.
The XENSIV™ MEMS microphone IM69D is a high performance digital MEMS microphone to deliver 105 dB dynamic range and high output linearity up to 130dBSPL. The application benefits are crystal clear audio signals, extended pick-up distance and sensitivity to both soft and loud signals – from whispered speech to rock concerts.
Infineon´s Dual Backplate (DBP) MEMS technology
Infineon’s Dual Backplate (DBP) unique MEMS technology provides crystal clear (SNR), distortion free (THD) audio signals. This can be achieved by Infineon’s MEMS structure of two backplates, one on each side of the membrane, which generate a fully differential signal.
