MP Series

MEMS Audio Sensor Omnidirectional Digital Microphone

STMicroelectronics

The MP series is a compact, low-power, omnidirectional, digital MEMS microphone. The STMicroelectronics MEMS microphone maintains ultra-low distortion at less than 10% up to very high external sound-pressure levels, enabling equipment such as smartphones and wearable devices to perform better when placing calls or recording audio in loud environments.

Product Description

The key is ST’s dedicated pre-amplifier design, which prevents saturation of the output signal even when background-noise levels are high, such as in concert venues, bars or clubs, or if the user is speaking loudly close to the microphone. In addition, omnidirectional sensitivity ensures excellent overall performance and versatility in mobile applications.
