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這是一種超小型、低功耗、全方位、數(shù)字MEMS麥克風(fēng)與電容式傳感元件和立體作戰(zhàn)能力的IC接口構(gòu)建。

傳感元件，能夠檢測(cè)聲波，是使用專門的硅微機(jī)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(shè)計(jì)專用的電路能夠提供外部PDM格式數(shù)字信號(hào)制作。
