IM73D122V01XTMA1

IM73D122V01XTMA1 is a IM73D122V01 series ultra-low noise digital XENSIVTM MEMS microphone. It 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. The powerful mix of ultra-high SNR and high sensitivity empowers high quality audio capturing for voice user interface applications in laptops, tablets or conferencing devices. Potential applications include laptops and tablets, conference systems, smart speakers, home automation and IoT devices, cameras.
