Product Highlights > MP23ABS1 High-Performance MEMS Audio Sensor

            MP23ABS1 High-Performance MEMS Audio Sensor
                    STMicroelectronics' compact, low-power microphone is built with a capacitive sensing element and an IC interface
    

Image of STMicroelectronics MP23ABS1 High-Performance MEMS Audio Sensor STMicroelectronics' MP23ABS1 sensing element, capable of detecting acoustic waves, is manufactured using a specialized silicon micromachining process to produce audio sensors. The MP23ABS1 has an acoustic overload point of 130 dBSPL with a typical 64 dB signal-to-noise ratio. The sensitivity of the MP23ABS1 is -38 dBV ±1 dB at 94 dBSPL, 1 kHz. The MP23ABS1 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.
