General Description

KX310CR-MZ is a MEMS capacitive 3-axis accelerometer

using KionixTM Technology.

(Note 1) Acceleration ranges of ±2

g, ±4 g and ±8 g are supported. Acceleration sensing is

based on the principle of a differential capacitance arising

from acceleration-induced motion of the sense element

which further utilize common mode cancellation to decrease

errors from process variation, temperature, and

environmental stress.

(Note 1) Kionix™ Technology is defined by the proprietary plasma

micromachining process and the technology to hermetically seal at

a wafer level by bonding the silicon lid wafer to the device wafer.
