Description
The MP23AB01DH 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 MP23AB01DH has sensitivity of 38 dB
±1 dB, an acoustic overload point of 135 dBSPL
with minimum 65 dB signal-to-noise ratio.
The MP23AB01DH has fully differential output in
order to minimize common mode noise.
The MP23AB01DH 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.
