  • The MP23ABS1 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 MP23ABS1 has an acoustic overload point of 130 dBSPL with a typical 64 dB signal-to-noise ratio.
    The sensitivity of the MP23ABS1 is -38 dBV ±1 dB @ 94 dBSPL, 1 kHz.
    The MP23ABS1 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 1.52 V - 3.6 V
    • Omnidirectional sensitivity
    • High signal-to-noise ratio
    • High acoustic overload point: 130 dBSPL typ.
    • Package compliant with reflow soldering
    • Enhanced RF immunity
    • Ultra-flat frequency response
    • Low latency
    • Ultra-low-power: 150 μA max
    • ECOPACK®, RoHS, and “Green” compliant
