100% tested in production
Qualified during product validation
The product is factory calibrated at 2.5 V in room temperature.
Typical values are not guaranteed.
Z-axis +1g position. Soldering process can cause offset shift which is typically less than 130 mg. Please see
TN68_CMA3000_Assembly_Instructions for further details.
Offset temperature error = {Vout(0g)-Offset} / Sensitivity [ g ]. Sensitivity = Calibrated sensitivity.
Offset= Calibrated offset.
Sensitivity = {Vout(+1g) - Vout(-1g)}/2 [V/g] .
Sensitivity temperature error = {[Vout(+1g)-Vout(-1g)]/2 - Sensitivity} / Sensitivity x 100% [%].
Sensitivity = Calibrated sensitivity.
Best fit straight line.
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.
Frequency responce -3dB roll off frequency = 1/(2π*32kΩ*C
