1 Guaranteed by measurement of initial offset and sensitivity.

2 Sensitivity is essentially ratiometric to VS. For VS = 3.0 V to 3.6 V, sensitivity is typically 185 mV/V/g to 190 mV/V/g.

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

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

5 Bandwidth = 1/(2 × π × 32 kΩ × C). For CX, CY = 0.002 μF, bandwidth = 2500 Hz. For CX, CY = 10 μF, bandwidth = 0.5 Hz. Minimum/maximum values are not tested.

6 Self-test response changes cubically with VS.

7 Larger values of CX, CY increase turn-on time. Turn-on time is approximately 160 × CX or CY + 4 ms, where CX, CY are in μF.
