MP23DB02MMTR

MP23DB02MMTR is an ultra-compact, low-power, omnidirectional, digital MEMS microphone built with a capacitive sensing element and an IC interface with optional stereo configuration. 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 the designing a dedicated circuit able to provide a digital signal externally in PDM format. It offers multiple performance modes enabled by different clock frequency ranges (power-down, low-power and normal mode). It is used in applications such as smartphones and handsets, laptop and notebook computers, wearable devices, digital still and video cameras, antitheft systems.
