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.
