Mingjiada Supply Recycle ST IIS3DWB Ultra-Wideband, Low-Noise 3-Axis Digital Accelerometer

Shenzhen Mingjiada Electronics Co., Ltd. — Long-term supplier of ST IIS3DWB ultra-wideband, low-noise 3-axis digital accelerometers, with genuine stock available. We also purchase IIS3DWB and related sensor stock at competitive prices, providing customers with one-stop component solutions.

Product Overview
The IIS3DWB is a high-performance 3-axis digital vibration sensor launched by STMicroelectronics. Featuring a System-in-Package (SiP) design, it integrates outstanding characteristics such as ultra-wide bandwidth, low noise, high stability and repeatable sensitivity.
The IIS3DWB is housed in a compact 14-pin LGA package (2.5 x 3 x 0.83 mm) and operates stably across an extended temperature range of –40°C to +105°C, making it particularly suitable for demanding applications such as industrial vibration monitoring and unmanned aerial vehicles (UAVs).

Key Technical Specifications of the IIS3DWB

Full-scale range: ±2/±4/±8/±16 g (user-selectable)
Bandwidth: DC to 6 kHz (±3 dB point)
Output data rate: 26.7 kHz
Noise density (3-axis): as low as 75 µg/√Hz
Noise density (single-axis): as low as 60 µg/√Hz
Operating Current: 1.1 mA (full performance in three-axis mode)
Supply Voltage: 2.1 V to 3.6 V
Package: LGA-14 (2.5 x 3 x 0.83 mm)
Operating Temperature: –40 °C to +105 °C
FIFO Buffer: 3 KB
Interface: SPI serial interface

Key Features of the IIS3DWB
Ultra-wide and flat frequency response: from DC to 6 kHz, delivering high-quality vibration data without the need for external signal conditioning circuits
Ultra-low noise: 75 µg/√Hz in three-axis mode and 60 µg/√Hz in single-axis mode, ensuring precise capture of faint vibration signals
Embedded digital functions: a 3 KB FIFO buffer prevents data loss, whilst interrupt functionality supports wake-up and activity detection
Embedded temperature sensor and self-test function, facilitating system integration and reliability verification
Low-power design: 1.1 mA operating current, suitable for battery-powered wireless sensor nodes

IIS3DWB Application Areas
Drones and Robots
With its ultra-wide 6 kHz bandwidth and low-noise characteristics, the IIS3DWB is capable of accurately capturing high-frequency vibration signals during drone flight. In the drone sector, this sensor can be used for:
Flight attitude monitoring and vibration analysis to enhance flight stability
Real-time vibration monitoring of motors and propellers to prevent mechanical failures
Auxiliary sensing for autonomous navigation and obstacle avoidance systems
The ST IIS3DWB has been widely adopted in robotics, drones, automotive electronics and other sectors.
