The Infineon high performance digital MEMS microphone is designed for applications where low self-noise, wide dynamic range, low distortions and a high acoustic overload point is required. The digital microphone contains an extremely low-noise preamplifier and a high-performance sigma-delta ADC. Different power modes can be selected in order to suit specific current consumption requirements.

Dynamic range of 93dB for best speech performance
Signal to noise ratio of 67dB
<1% total harmonic distortions up to high SPL levels
Acoustic overload point at 120dBSPL
Increased sensitivity for best performance with 16-bit CODECs
Automotive qualification
Close sensitivity and phase matching for use in arrays
Flat frequency response with low frequency roll off and very fast analog to digital conversion speed for best ANC performance
Digital PDM output
Extended availability to match automotive design cycles
