ECOPACK, RoHS, and “Green” compliant Applications Product status link IMP23ABSU Product summary Order code IMP23ABSU IMP23ABSUTR Temp. range [°C] -40 to +85 Package (3.5 x 2.65 x 0.98) mm Packing Tray Product label Tape and reel • • • • • • • • Condition monitoring of industrial equipment Leak detection Electrical arcing Smart medical instruments Wearable devices Hearables Smart speakers Active noise-canceling headsets Description 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.
