The ADXL327 is a small, low power, 3-axis accelerometer with features such as small size, low power consumption, and single-supply operation. It is suitable for cost-sensitive, low power motion and tilt sensing applications.
The ADXL327 accelerometer from Analog Devices provides three‑axis acceleration sensing in a compact 4 mm × 4 mm × 1.45 mm LFCSP package. It operates from a single supply of 1.8 V to 3.6 V and draws only 350 µA typical current, making it suitable for battery‑powered devices.
The device offers selectable bandwidth from 0.5 Hz to 1600 Hz (X/Y) or 550 Hz (Z) using external capacitors, and includes built‑in self‑test, low‑noise performance, and robust ESD protection. Detailed pinout, electrical specifications, and layout recommendations are provided for designers.
