IM69D120
High performance digital XENSIVTM MEMS microphone
Description
The IM69D120 is designed for applications where low self-noise (high SNR), wide dynamic range, low distortions and a high acoustic overload point is required. Infineon's Dual Backplate MEMS technology is based on a miniaturized symmetrical microphone design, similar as utilized in studio condenser microphones, and results in high linearity of the output signal within a dynamic range of 95dB. The microphone distortion does not exceed 1% even at sound pressure levels of 118dBSPL. The flat frequency response ( 28Hz low-frequency roll-off) and tight manufacturing tolerance result in close phase matching of the microphones, which is important for multi-microphone (array) applications.
