Description

The MP34DT06J 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 MP34DT06J is a low-distortion digital microphone with a 64 dB signal-to-noise

ratio and –26 dBFS ±1 dB sensitivity.

The MP34DT06J 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.
