IM69D120V01XTSA1

IM69D120V01XTSA1 is a high-performance digital XENSIV™ MEMS microphone. It is designed for applications where low self-noise, wide dynamic range, low distortions and a high acoustic overload point are required. It is based on a miniaturized symmetrical microphone design, similar as that 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 and tight manufacturing tolerance result in close phase matching of the microphones, which is important for multi-microphone applications. Typical applications include devices with voice user interface, smart speakers, home automation, IoT devices, active noise cancellation headphones and earphones, high-quality audio capturing, conference systems, cameras and camcorders, and industrial or home monitoring with audio pattern detection.
