Description
The MP23AB01DM 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 MP23AB01DM has an acoustic overload
point of 130 dBSPL with a typical 64 dB signal-to-
noise ratio.
The MP23AB01DM has fully differential output in
order to minimize common-mode noise.
The sensitivity of MP23AB01DM is -38 dBV
±3 dB @ (0 dB = 1 V/Pa), 1 kHz.
The MP23AB01DM 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.
