Description
The MP34DT01-M is an ultra-compact, low-
power, omnidirectional, digital MEMS microphone
built with a capacitive sensing element and an IC
interface.
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 MP34DT01-M has an acoustic overload point
of 120 dBSPL with a 61 dB signal-to-noise ratio
and –26 dBFS sensitivity.
The MP34DT01-M is available in a top-port, SMD-
compliant, EMI-shielded package and is
guaranteed to operate over an extended
temperature range from -40 °C to +85 °C.
