MP34DT02TR

STMICROELECTRONICS  MP34DT02TR  音频控制器, MEMS 麦克风, 1.64V 至 3.6V, HCLGA, 4 引脚, -40 °C

The MP34DT02 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 MP34DT02 has an acoustic overload point of 120 dBSPL with a 60 dB signal-to-noise ratio and –26 dBFS sensitivity.

The MP34DT02 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.
