Industrial vibration sensing simplified

29 May 2026 Analogue, Mixed Signal, LSI

The IIS3DWBG1 from STMicroelectronics is a high performance, three-axis digital vibration sensor engineered for demanding industrial applications where accurate motion monitoring is essential. Designed with an ultra-wide bandwidth and exceptionally low noise characteristics, the device is particularly suited to predictive maintenance, condition monitoring, and vibration analysis in industrial machinery and electric or hybrid vehicles.

Offering a selectable full-scale range of ±2 g, ±4 g, ±8 g, or ±16 g, the sensor can measure accelerations across a broad operating spectrum with a frequency response extending from DC to 6 kHz. This enables highly detailed vibration capture, even in fast-moving systems.

The IIS3DWBG1 integrates a 3 KB FIFO buffer, embedded temperature sensor, self-test functionality, and configurable filtering options, reducing processing demands on the host system. Operating from 2,1 V to 3,6 V and consuming just 1,1 mA in full three-axis mode, the compact LGA-14L packaged device delivers reliable performance across an extended temperature range.
