MP34DB01音频设备产品的麦克风规格书PDF中文资料

MP34DB01属于音频设备产品的麦克风。由意法半导体集团制造生产的MP34DB01麦克风麦克风是将声音转换成电信号以便存储、传输和/或转播的换能器。范围从大型悬臂式麦克风到常用的小型 MEMS 产品，并且可根据阻抗、额定电压、灵敏度、频率范围、端口位置、整体尺寸和安装类型进行区分。输出接口提供模拟、I2S、PDM 和 TDM 等种类。

描述 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.
