  • The MP34DT05-A is an ultra-compact, low-power, omnidirectional, digital MEMS 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 dedicated to producing audio sensors.
    The IC interface is manufactured using a CMOS process that allows designing a dedicated circuit able to provide a digital signal externally in PDM format.
    The MP34DT05-A is a low-distortion digital microphone with a 64 dB signal-to-noise ratio and –26 dBFS ±3 dB sensitivity.
    The MP34DT05-A is available in a top-port, SMD-compliant, EMI-shielded package and is guaranteed to operate over an extended temperature range from -40 °C to +85 °C.

    Key Features

    • Single supply voltage
    • Low power consumption
    • AOP = 122.5 dBSPL
    • 64 dB signal-to-noise ratio
    • Omnidirectional sensitivity
    • –26 dBFS ±3 dB sensitivity
    • PDM output
    • HCLGA package
      • Top-port design
      • SMD-compliant
      • EMI-shielded
      • ECOPACK, RoHS, and “Green” compliant
