Cross-Axis Sensitivity
1. For a loaded output, the measurements are observed after an RC filter consisting of a 1.0 kΩ resistor and a 0.1 µF capacitor on V
2. These limits define the range of operation for which the part will meet specification.
3. Within the supply range of 2.2 and 3.6 V, the device operates as a fully calibrated linear accelerometer. Beyond these supply limits the device
4. This value is measured with g-Select in 2.5g mode.
5. The device can measure both + and – acceleration. With no input acceleration the output is at midsupply. For positive acceleration the output
6. These values represent the 10th percentile, not the minimum.
7. These values represent the 90th percentile, not the maximum.
8. The response time between 10% of full scale V
9. The response time between 10% of full scale Sleep Mode input voltage and 90% of the final operating output voltage.
