The MP34DB02 is an ultra-compact, low-power, omnidirectional, digital MEMS microphone built with a capacitive sensing element and an IC interface with stereo operation capability.

The sensing element, capable of detecting acoustic waves, is manufactured using a specialized silicon micromachining process dedicated to produce audio sensors.

The IC interface is manufactured using a CMOS process that allows designing a dedicated circuit able to provide a digital signal externally in PDM format.

The MP34DB02 has an acoustic overload point of 120 dBSPL with a best on the market 62.6 dB signal-to-noise ratio and -26 dBFS sensitivity.

The MP34DB02 is available in a bottom-port, SMD-compliant, EMI-shielded package and is guaranteed to operate over an extended temperature range from -40 °C to +85 °C.

mp34db02这是一种超小型、低功耗、全方位、数字MEMS麦克风与电容式传感元件和立体作战能力的IC接口构建。

传感元件，能够检测声波，是使用专门的硅微机械加工工艺，专门生产音频传感器制造的。

IC接口是使用CMOS工艺，设计专用的电路能够提供外部PDM格式数字信号制作。

有120的mp34db02 dBSPL与市场上最好的62.6 dB的信噪比和灵敏度26 dBfs声学超载点。
