The measuring range is tested on sensing element level. FS = 2g. 4) Includes effects over supply voltage, temperature and life time 6) Sensitivity = {Count(+1g) - Count(-1g)}/2 [Count/g]. 7) From straight line through sensitivity calibration (+1g, -1g) points. 8) The cross-axis sensitivity determines how much acceleration, perpendicular to the measuring axis, couples to the output. The total cross-axis sensitivity is the geometric sum of the sensitivities of the two axes which are perpendicular to the measuring axis. The angular alignment error between X, Y and Z axis is included into the cross axis sensitivity. 9) Frequency responses according to Figure 4. 10) Average noise/axis over the measurement bandwidth defined as )222(3 znynxn , where nx, ny and nz are the measured signal's standard deviation due to noise in x, y and z directions. 11) Settling error less than 1% of FS.
