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
dedicatedwww.DataSheet.net/ 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.

Power supply decoupling capacitors (100 nF ceramic, 10 µF ceramic) should be placed as
near as possible to pin 3 of the device (common design practice).
The L/R pin must be connected to Vdd or GND (refer to Table 8).
