Description
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.
Infineon's MEMS technology 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.
The analog microphone ASIC contains an extremely low-noise preamplifier.
The tight manufacturing tolerance, combined with the fact that each device is calibrated with an advanced Infineon calibration
algorithm, results in small sensitivity and phase matching tolerances. This makes it well suited for beam forming arrays and
multi-microphone applications.
