1 / 17 page  April 2016 DocID026103 Rev 2 1/17 This is information on a product in full production. www.st.com MP34DB02 MEMS audio sensor omnidirectional digital microphone Datasheet - production data Features • Single supply voltage • Low power consumption • 120 dBSPL acoustic overload point • 62.6 dB signal-to-noise ratio • Omnidirectional sensitivity • –26 dBFS sensitivity • PDM single-bit output with option for stereo configuration • RHLGA package − Bottom-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 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.
