Description
The MP34DT05-A 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 producing 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 MP34DT05-A is a low-distortion digital microphone with a 64 dB signal-to-noise
ratio and –26 dBFS ±3 dB sensitivity.
The MP34DT05-A 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.
