Description
The MP23ABS1 is a compact, low-power
microphone built with a capacitive sensing
element and an IC interface.
The sensing element, capable of detecting
acoustic waves, is manufactured using a
specialized silicon micromachining process to
produce audio sensors.
The MP23ABS1 has an acoustic overload point of
130 dBSPL with a typical 64 dB signal-to-noise
ratio.
The sensitivity of the MP23ABS1 is -38 dBV
±1 dB @ 94 dBSPL, 1 kHz.
The MP23ABS1 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.

Applications
 Mobile phones
 Wearables
 Hearables
 Smart speakers
 Active noise-canceling headsets
