1 Defined as coupling between any two axes.

2 Sensitivity is essentially ratiometric to VS.

3 Defined as the output change from ambient temperature to maximum temperature or from ambient temperature to minimum temperature.

4 Actual frequency response controlled by user-supplied external filter capacitors (CX, CY, and CZ).

5 Bandwidth with external capacitors = 1/(2π × 32 kΩ × Cx).

6 Self-test response changes cubically with VS.

7 Tested at 3.0 V and guaranteed by design only (not tested) to work over the full voltage range from 1.8 V to 3.6 V.

8 Turn-on time is dependent on CX, CY, and CZ and is approximately 160 × (CX or CY or CZ) + 1, where CX, CY, and CZ are in μF and the resulting turn-on time is in ms.
