STMicroelectronics IIS3DWB

The IIS3DWB is a system-in-package featuring a 3-axis digital vibration sensor with low noise over an ultra-wide 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 monitoring in industrial applications.

Key features

• 3-axis vibration sensor with digital output
• Ultra-wide and flat frequency response up to 6kHz
• High stability of the sensitivity over temperature and against mechanical shocks
• Extended temperature range from -40 to +105 °C
• Minimum 10 year Longevity

Additional features

• 3-axis vibration sensor with digital output
• User-selectable full-scale: ±2/±4/±8/±16 g
• Ultra-low 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
• A low-pass or high-pass filter with a selectable cut-off frequency
• Interrupts for wake-up / activity - inactivity / FIFO thresholds
• Embedded FIFO: 3 kB
• Embedded temperature sensor
• Embedded self-test
• Supply voltage: 2.1 V to 3.6 V
• Compact package: LGA 2.5 x 3 x 0.83 mm 14-lead
