IM69D127V11XTMA1

IM69D127V11XTMA1 is an IP57 dust and water-resistant PDM digital XENSIV™ MEMS microphone. It is an ultra-high performance digital PDM MEMS microphone designed for applications that require a very high SNR (low self-noise) and low distortion and which is also IP57 robust to dust and water. Best-in-class signal-to-noise ratio of 69dB(A) enables far-field and low-volume audio pick-up. The flat frequency response (40Hz low-frequency roll-off) and tight manufacturing tolerance improve the performance of multi-microphone applications. The digital microphone ASIC contains an extremely low-noise preamplifier and a high-performance sigma-delta ADC. Typical applications include active noise cancellation headphones and wireless earbuds, devices with voice user interface, smart speakers, home automation, IoT devices, high-quality audio capturing, cameras, laptops and tablets, and conference systems.
