GMA302F ±16g Tri-Axial Digital Accelerometer General Introduction GMA302F is a tri-axial digital accelerometer with ±16g dynamIC range and 13-bit ADC resolution. It integrates a MEMS sensing element and a CMOS conditioning IC in a compact 3×3×1 mm 3 package. The high resolution makes feasible preciseapplications like e-Compass tilt compensation. The wide sensing range further opens enough windows for motion detection. Finally the small form factor makes it an easy fit-in for compact applications like wearables. Features
