Overview
The ADXL367BCCZ-RL7, produced by Analog Devices Inc., is an ultralow power, 3-axis microelectromechanical systems (MEMS) accelerometer. This device is designed for applications requiring high sensitivity and low power consumption. It operates within a wide supply voltage range of 1.1 V to 3.6 V, making it suitable for single-cell battery operation. The ADXL367 features advanced power-saving capabilities, including a deep 512-sample FIFO, motion-activated wake-up modes, and an internal power supply regulation for high power supply rejection ratio (PSRR).
