1 / 21 page  November 2016 DocID029902 Rev 1 1/21 This is information on a product in full production. www.st.com MP34DT05 MEMS audio sensor omnidirectional digital microphone Datasheet - production data Features • Single supply voltage • Low power consumption • AOP = 122.5 dBSPL • 64 dB signal-to-noise ratio • Omnidirectional sensitivity • –26 dBFS ± 3 dB 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 MP34DT05 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 MP34DT05 is a low-distortion digital microphone with a 64 dB signal-to-noise ratio and –26 dBFS ± 3 dB sensitivity. The MP34DT05 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.
