IM69D127V11
IM69D127V11 is IP57 dust and water resistant PDM digital MEMS microphone manufactured by Infineon.
Description
The IM69D127V11 is an ultra-high performance digital PDM MEMS microphone designed for applications which require a very high SNR (low self-noise) and low distortion (high AOP) and which is also IP57 robust to dust and water. Best-in-class signal-to-noise ratio (SNR) of 69d B(A) enables far field and low volume audio pick-up. The flat frequency response (40Hz low-frequency roll-off) and tight manufacturing tolerance improve performance of multi-microphone (array) applications. The digital microphone ASIC contains an extremely low-noise preamplifier and a high-performance sigma-delta ADC. Different power modes can be selected in order to suit specific clock frequency and current consumption requirements. Each IM69D127V11 microphone is calibrated with an advanced Infineon calibration algorithm, resulting in low sensitivity tolerances (± 1d B).
