MP34DT01-M MEMS audio sensor omnidirectional digital microphone Datasheet - production data VoIP Speech recognition A/V eLearning devices Gaming and virtual reality input devices Digital still and video cameras Antitheft systems HCLGA (3 x 4 x 1.06 4LD) Features Single supply voltage Low power consumption 120 dBSPL acoustic overload point 61 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 Description The MP34DT01-M is an ultra-compact, lowpower, 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-M has an acoustic overload point of 120 dBSPL with a 61 dB signal-to-noise ratio and –26 dBFS sensitivity. The MP34DT01-M 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.
