Description
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 64 dB 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.
