IM69D130 XENSIV™ MEMS microphone with 105dB dynamic range and high output linearity up to 130dBSPL
Overview
IM69D130 is a high performance digital MEMS microphone making use of Infineon’s Dual Backplate MEMS technology to deliver 105dB dynamic range and high output linearity up to 130dBSPL. The application benefits are crystal clear audio signals, extended pick-up distance and sensitivity to both soft and loud signals - from whispered speech to rock concerts.
Summary of Features
