MP34DB02:MEMS audio sensor omnidirectional stereo digital microphone

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.
