MP34DT01-M中文资料MEMS audio sensor omnidirectional stereo digital microphone数据手册ST规格书

描述 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.
