IM69D129F – Ultra-low power digital XENSIV™ MEMS microphone Discover the IM69D129FV01 – a low power digital XENSIV™ MEMS microphone designed for applications which require a digital PDM MEMS microphone with high SNR (low self-noise), low distortion (high AOP), and very low current consumption. SNR of 69dB(A) enables far-field & low volume audio pick-up. The flat frequency response (11 Hz low-frequency roll-off) & tight manufacturing tolerance improve performance of multi-microphone (array) applications.
