1 Guaranteed by measurement of initial offset and sensitivity.
2 Sensitivity varies with VS. At VS = 3 V, sensitivity is typically 28%/g.
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 capacitor (CX, CY).
5 Bandwidth = 1/(2 × π × 32 kΩ × C). For CX, CY = 0.002 µF, Bandwidth = 2500 Hz. For CX, CY = 4.7 µF, Bandwidth = 1 Hz. Minimum/maximum values are not tested.
6 Self-test response changes with VS. At VS = 3 V, self-test output is typically 8%.
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.
