IM68A130AXTMA1

IM68A130AXTMA1 is an AEC-Q103 qualified high performance analogue XENSIV™ MEMS microphone. The device is designed for applications where low self-noise (high SNR), wide dynamic range, low distortions and a high acoustic overload point is 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. Potential application includes active noise cancellation / Road noise cancellation (ANC/RNC), hands free calling, emergency call, voice control, siren detection, road condition detection.
