MP23AB01DMTR

High-performance MEMS audio sensor: fully differential analog bottom-port microphone

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.
