Overview
The ADXL359BCCZ-RL, produced by Analog Devices Inc., is a low noise density, low 0 g offset drift, and low power 3-axis microelectromechanical system (MEMS) accelerometer. This device is designed to offer industry-leading noise performance, minimal offset drift over temperature, and long-term stability, making it ideal for precision applications with minimal calibration. The ADXL359 supports selectable measurement ranges of ±10 g, ±20 g, and ±40 g, and it is particularly suited for environments with high vibration, such as airborne inertial measurement units (IMUs) and wireless condition monitoring.
