Microphone coupon board based on the IMP23ABSU analog MEMS microphone

The STEVAL-MIC007V1 is a daughterboard containing 4 IMP23ABSU MEMS microphones.

The coupon concept allows easy performance testing of ST MEMS microphones. It is possible to detach the single PCBs hosting each microphone.

  • 4 x IMP23ABSU bottom port analog MEMS microphones
  • Vsupply from 1.52 to 3.6 V
  • 130 dBSPL acoustic overload point
  • Omnidirectional sensitivity
  • Enhanced RF immunity
  • Ultrasound bandwidth (up to 80 kHz)
  • Ultra-low-power: 150 μA max
  • Sensitivity -38 dBV 1 dB
  • RoHS compliant
