IM72D128V – Ultra-low power digital XENSIV™ MEMS microphone Discover the IM72D128V, an ultra-high performance XENSIV™ MEMS microphone designed for applications which require a digital PDM MEMS microphone with high SNR (low self-noise), low distortion (high AOP), & very low current consumption. SNR of 71.5dB(A) enables far-field & low volume audio pick-up. The flat frequency response (11Hz low-frequency roll-off) & tight manufacturing tolerance improve performance of multi-microphone (array) applications.
