The ADXL325 is a small, low-power, complete 3-axis accelerometer with signal-conditioned voltage outputs. The product measures acceleration with a minimum full-scale range of ±5 g. It can measure the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration, resulting from motion.
The ADXL325 accelerometer provides three‑axis acceleration measurement with signal‑conditioned voltage outputs. It operates from a single supply of 1.8 V to 3.6 V, draws about 350 µA typical current, and fits in a 4 mm × 4 mm × 1.45 mm LFCSP package. Bandwidth for the X and Y axes can be set up to 1.6 kHz, while the Z axis can reach 550 Hz, using a single external capacitor per axis.
The device is rated for ±5 g full‑scale measurement, 10,000 g shock survival, and operates from –40 °C to +85 °C. It includes self‑test pins, low noise density (250 µg/√Hz), and is RoHS/WEEE compliant, making it suitable for mobile, gaming, and health‑monitoring applications.
