cross-axis sensitivity terms known as Sxy, Sxz, Syx, Syz, Szx and Szy. The cross-axis

sensitivity specification represents the maximum of these six terms.

Output data rate, decimation factor, and power consumption

The Output Data Rate (ODR) defines the rate at which acceleration data is output from

FXLS8964AF. Depending on the operating mode and ODR that is selected, different

decimation factors (oversampling ratios) are applied. The decimated output data is

supplied at the ODR rate, even though multiple samples of the sensor data may have

been used to calculate this average result. In FXLS8964AF lowest power mode, the

decimation factor is always 1, leading to the best power performance at the expense of

the poorest noise (resolution) performance. In high performance mode, the decimation

factor is automatically increased to the maximum possible value for a given ODR,

resulting in the best noise (resolution) performance at the expense of the poorest power

consumption. In motion detection mode with BT_MODE=VDD, use of HPM or FPM mode

is not advised. Only the default LPM mode should be used.

9.2 Absolute maximum ratings

Absolute maximum ratings are the limits the device can be exposed to without damage.

Functional operation at absolute maximum rating is not guaranteed.

Although this device contains circuitry to protect against damage due to high static

voltage or electrostatic fields, it is advised that normal precautions be taken to avoid

application of any voltage higher than the maximum-rated voltage.
