MP34DB01

MP34DB01 MEMS audio sensor omnidirectional digital microphone 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 RHLGA 3x4x1 4LD Description The MP34DB01 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 MP34DB01 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 MP34DB01 is available in a bottom-port, SMD-compliant, EMI-shielded package and is guaranteed to operate over an extended temperature range from -30 °C to +85 °C.
