Infineon Technologies MEMS microphone IM67D130A

Our high-performance digital MEMS microphones are suited to all applications inside and outside the car, where the best audio performance in harsh automotive environments is required. These automotive microphones enable distortion-free audio capturing for all speech-related applications improving speech intelligibility for voice recognition algorithms. In addition, they perfectly support acoustic noise cancellation with its flat frequency and stable phase response. Other highlights include close sensitivity and phase matching, making automotive XENSIV™ MEMS microphones ideal for beamforming arrays.
