Overview
The ADXL1004BCPZ, produced by Analog Devices Inc., is a low noise, single-axis, MEMS (Microelectromechanical Systems) accelerometer. This device is designed to provide an analog output proportional to mechanical vibration, making it highly suitable for vibration measurements in high bandwidth applications. The ADXL1004BCPZ features a high g range of ±500 g, ultralow noise density, and a wide linear frequency response range, making it ideal for applications such as condition monitoring, predictive maintenance, and asset health monitoring.
