STMicroelectronics’ MP23AB02B is a compact, low-power microphone built with a low-profile MEMS sensing element. The sensing element, capable of detecting acoustic waves, is manufactured using a special silicon micromachining process.
The MP23AB02B has an acoustic overload point of 125dB sound pressure level and features a 64dB signal-to-noise ratio. Sensitivity is rated at -38dBV/PA for sound at a frequency of 1kHz.
The typical current drawn by the MP23AB02B in operation is just 150μA with a 2V supply. It is guaranteed to operate over an extended temperature range from -40°C to 85°C.
The device is housed in a three-lead land grid array package with a metal cap. It measures 3.4mm x 2.5mm x 1mm.
- Single supply-voltage range: 1.6V to 3.6V
- Omnidirectional sensitivity
- High bandwidth
- Low distortion
- Space-constrained applications
- Consumer electronics devices
The STEVAL-MKI139V3 is a daughterboard containing four MP23AB02B microphones. It is possible to detach from the board the single PCBs hosting each microphone.
