Tri-Axis, User Selectable ± 2g, 4g, 8g, 16g, Digital (I2C) Interface and Motion

The KXTJ3-1057 is a tri-axis ±2g, ±4g, ±8g or ±16g silicon micromachined accelerometer. The sense element is fabricated using Kionix’s proprietary plasma micromachining process technology. Acceleration sensing is based on the principle of a differential capacitance arising from acceleration-induced motion of the sense element, which further utilizes common mode cancellation to decrease errors from process variation, temperature, and environmental stress.
