MP23AB02BMEMS 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 125 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.
- Single supply voltage operation
- Low power consumption
- Omnidirectional sensitivity
- High signal-to-noise ratio
- High bandwidth
- Package compliant with reflow soldering
