MP34DT01 MEMS audio sensor omnidirectional digital microphone Datasheet - production data Features Single supply voltage Low power consumption 120 dBSPL acoustic overload point 63 dB signal-to-noise ratio Omnidirectional sensitivity –26 dBFS sensitivity PDM output HCLGA package − Top-port design − SMD-compliant − EMI-shielded − ECOPACK®, RoHS, and “Green” compliant Applications Mobile terminals Laptop and notebook computers Portable media players VoIP Speech recognition A/V eLearning devices Gaming and virtual reality input devices Digital still and video cameras Antitheft systems Description 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, SMDcompliant, EMI-shielded package and is guaranteed to operate over an extended temperature range from -40 °C to +85 °C.
