MEMS microphones target all audio applications where small size, high sound quality, reliability and affordability are key requirements. Based on Omron’s sensor technology, our microphones meet price points set by the traditional electret condenser microphones (ECM), while featuring superior reliability and robustness.
ST's MEMS mics are designed in industry-unique, innovative plastic packaging that offers slimmer form factors, and outperforms traditional metallic lid devices in durability. Both analog- and digital-input top and bottom port solutions are available.
Their best-in-class SNR makes ST’s MEMS microphones suitable for applications beyond typical consumer applications, such as phonometers and sound-level meters that require a high dynamic range.
ST’s MEMS microphones perfectly pair with our latest generation Sound Terminal® audio processing devices that feature a dedicated built-in interface for direct connection of a MEMS microphone, saving part count and cost.
MP23AB02B MEMS audio sensor
The MP23AB02B is a compact, low-power microphone built with a low-profile sensing element. The sensing element, capable of detecting acoustic waves, is manufactured using a specialized silicon micromachining process to produce audio sensors.
The MP23AB02B has an acoustic overload point of 124 dBSPL with a 64dB signal-to-noise ratio.
The MP23AB02B is available in a package compliant with reflow soldering and is guaranteed to operate over an extended temperature range from -40 °C to +85 °C.
