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

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.

Key Features

  • Single supply voltage operation
  • Fully differential output
  • Omnidirectional sensitivity
  • High signal-to-noise ratio
  • High bandwidth
  • Package compliant with reflow soldering
