STMicroelectronics IIS3DWB10IS Accelerometer
STMicroelectronics IIS3DWB10IS Accelerometer is integrated with ultrawide bandwidth, low-noise, 3-axis digital vibration sensor with Intelligent Sensor Processing Unit (ISPU). This accelerometer offers a selectable full-scale acceleration range of ±50g/±100g/±200g and is capable of measuring accelerations with a bandwidth above 10kHz. The IIS3DWB10IS accelerometer embeds a new ST category of processing, Intelligent Sensor Processing Unit (ISPU), to support real-time applications that rely on sensor data. This accelerometer provides a self-test capability that allows checking the sensor's functionality in the final application. The IIS3DWB10IS accelerometer is available in a 16-lead plastic, Land Grid Array (LGA) package and operates over an extended temperature range from -40°C to +125°C. Typical applications include vibration monitoring, test and measurements, condition monitoring, and predictive maintenance.
