IM72D128

Active and preferred

The IM72D128V01 is an ultra-high performance digital microphone designed for applications requiring high SNR and low distortions. Based on Infineon's Sealed Dual Membrane (SDM) MEMS technology, it delivers high IP57 ingress protection. The flat frequency response and tight manufacturing tolerance improve multi-microphone (array) applications.
