STMicroelectronics MP45DT02 compact low power top port omnidirectional digital MEMS microphone.
The device has a built-in sensing element and a stereo IC interface. The sensing element capable of detecting sound waves is manufactured using a special silicon micromachining process to produce audio sensors. The IC interface is manufactured using a CMOS process, which allows the design of dedicated circuits to externally provide digital signals in PDM format.
Typical applications include mobile terminals, laptops and notebooks, portable media players, VoIP systems, voice recognition, A / V e-learning devices, gaming and virtual reality input devices, digital cameras and video cameras, and anti-theft systems.
