The MP34DT01 is an ultra-compact, low-power, omnidirectional, digital MEMS microphone built with a capacitive sensing element and an IC interface.

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 MP34DT01 has an acoustic overload point of 120 dBSPL with a 63 dB signal-to-noise ratio and –26 dBFS sensitivity.

The MP34DT01 is available in a top-port, SMD-compliant, EMI-shielded package and is guaranteed to operate over an extended temperature range from -40 °C to +85 °C.

mp34dt01這是一種超小型、低功耗、全方位、數(shù)字MEMS麥克風與電容式傳感元件和一個集成電路接口構建。

傳感元件，能夠檢測聲波，是使用專門的硅微機械加工工藝，專門生產(chǎn)音頻傳感器制造的。

IC接口是使用CMOS工藝，設計專用的電路能夠提供外部PDM格式數(shù)字信號制作。
