MEMS audio sensor high-performance analog bottom-port microphone

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.

Key Features

  • Single supply voltage operation
  • Low power consumption
  • Omnidirectional sensitivity
  • High signal-to-noise ratio
  • High bandwidth
  • Package compliant with reflow soldering
