IM66D130AXTMA1

IM66D130AXTMA1 is an AEC-Q103 qualified high-performance digital XENSIV™ MEMS microphone. It is designed for applications where low self-noise (high SNR), wide dynamic range, low distortions, and a high acoustic overload point are required. The low cut-off frequency (LFRO) makes it a well-suited device for active noise cancelling (ANC) applications. It is based on a miniaturized microphone design and results in high linearity of the output signal within a high dynamic range. With its low equivalent noise floor, the microphone is no longer the limiting factor in the audio signal chain and enables higher performance of voice recognition algorithms. It is used in applications such as active noise cancellation / road noise cancellation (ANC/RNC), hands-free calling / voice control, emergency call, siren detection, and road condition detection.
