Overview
The ADXL1004BCPZ-RL, produced by Analog Devices Inc., is a low noise, single-axis, MEMS (Microelectromechanical Systems) accelerometer. It is designed to provide an analog output proportional to mechanical vibration, making it ideal for high bandwidth applications such as vibration analysis and predictive maintenance. The device features a high g range of ±500 g and a resonant frequency of 45 kHz, enabling the measurement of vibration patterns caused by small moving components like internal bearings. It operates over a wide temperature range of −40°C to +125°C and is available in a 32-lead LFCSP package measuring 5 mm × 5 mm × 1.80 mm.
