MP34DB01 MEMS audio sensor omnidirectional digital microphone

Description
The MP34DB01 is a compact, low-power, bottom port, omnidirectional digital MEMS microphone. The MP34DB01 is 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 dB signal-to-noise ratio and -26 dB sensitivity.

The MP34DB01 is available in an SMD-compliant package and it is guaranteed to operate over an extended temperature range from -30 °C to +85 °C.
