IMP23ABSU – Analog bottom port microphone with frequency response up to 80kHz for Ultrasound analysis and Predictive Maintenance applications

The IMP23ABSU 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 IMP23ABSU has an acoustic overload point of 130 dBSPL with a typical 64 dB signal-to-noise ratio. The sensitivity of the IMP23ABSU is -38 dBV ±1 dB @ 94 dBSPL, 1 kHz.

The IMP23ABSU 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
  • Ultrasound bandwidth (up to 80 kHz)
  • Low latency
  • Ultra-low-power: 150 µA max.
  • ECOPACK, RoHS, and “Green” compliant
