INFINEONIM67D120AXTSA15 Pin Microphone, Omni-Directional, Surface Mount, Digital (PDM) Output, PG-LLGA-5-4, 1.62-3.6V

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
