Product overview
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.
