Check & Measurement
The STMicroelectronics MP23ABS1 is a compact, low-power microphone constructed with a capacitive sensing ingredient and an IC interface. The system is out there from RS Elements.
The sensing ingredient, in a position to detect acoustic waves, is constructed utilizing a specialised silicon micromachining course of to provide audio sensors.
The system supplies an acoustic overload level of 130dBSPL with a typical 64dB signal-to-noise ratio.
The sensitivity of the system is -38dBV ±1dB @ 94dBSPL, 1kHz.
The system is offered in a package deal compliant with reflow soldering and is assured to run over an prolonged temperature vary from -40C to +85C.
Typical functions embody cellphones, wearables, hearables, sensible audio system, and energetic noise-cancelling headsets.
