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.
