1. For a loaded output, the measurements are observed after an RC filter consisting of a 1.0 kâ¦ resistor and a 0.1 ÂµF capacitor on VDD-GND.

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

may operate as a linear device but is not guaranteed to be in calibration.

4. This value is measured with g-Select in 2.5g mode.

5. The device can measure both + and â acceleration. With no input acceleration the output is at midsupply. For positive acceleration the output

will increase above VDD/2. For negative acceleration, the output will decrease below VDD/2.

6. The response time between 10% of full scale Vdd input voltage and 90% of the final operating output voltage.

7. The response time between 10% of full scale Sleep Mode input voltage and 90% of the final operating output voltage.

8. A measure of the deviceâs ability to reject an acceleration applied 90Â° from the true axis of sensitivity.
