Ultra-low noise digital XENSIVTM MEMS microphone IM73D122 is designed for applications which require a very high SNR (low self-noise) and a high sensitivity. The flat frequency response (20Hz low-frequency roll-off) and tight manufacturing tolerance improve performance of multi-microphone (array) applications. This microphone is based on Infineon’s new Sealed Dual Membrane MEMS technology which delivers high ingress protection (IP57) at a microphone level.
