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.
