IIS3DWB 3-axis digital vibration sensor

The IIS3DWB is a system-in-package featuring a 3-axis digital vibration sensor with low noise over an ultrawide and flat frequency range. The wide bandwidth, low noise, very stable and repeatable sensitivity, together with the capability of operating over an extended temperature range (up to +105 °C), make the device particularly suitable for vibration monit.

Features

• 3-axis vibration sensor with digital output
• User-selectable full scale: ±2/±4/±8/±16 g
• Ultrawide and flat frequency response range: from dc to 6 kHz (±3 dB point)
• Ultralow noise density: down to 75 µg/√Hz in 3-axis mode / 60 µg/√Hz in single-axis mode
• High stability of the sensitivity over temperature and against mechanical shocks
• Extended temperature range from -40 to +105 °C
• Low power: 1.1 mA with all 3 axes delivering full performance
• SPI serial interface
• Low-pass or high-pass filter with selectable cutoff frequency
• Interrupts for wake-up / activity - inactivity / FIFO t.
