1 Defined as coupling between any two axes.

2 Sensitivity is essentially ratiometric to VS.

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

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

5 Bandwidth with external capacitors = 1/(2 × π × 32 kΩ × C). For CX, CY = 0.003 μF, bandwidth = 1.6 kHz. For CZ = 0.01 μF, bandwidth = 500 Hz. For CX, CY, CZ = 10 μF,

bandwidth = 0.5 Hz.

6 Self-test response changes cubically with VS.

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