The Infineon MEMS microphone is a high performance, single ended, analogue MEMS microphone designed for applications which require a low LFRO, a high SNR and low distortion. The high signal to noise ratio of 68dB enables far field and low volume audio pick up. The flat frequency response and tight manufacturing tolerance improve the performance of Active Noise Cancellation and multi microphone array applications. The high performance analogue microphone ASIC contains an extremely low noise preamplifier providing constant current consumption over VDD.
