Table 4. Operating Characteristics
Unless otherwise noted: -40°C < T
Typical values are at AV
Notes
1. These parameters are tested in production at final test.
2. Assuming VDD power on slope is < 1 ms.
3. A measure of the devices ability to reject an acceleration applied 90° from the true axis of sensitivity.
4. Noise is defined as quantiles given to a sample size. These are the occurrences of noise: 94% = ±1 count, 5% = ±2 counts, and 1% = ±3
