Table 2. Operating Characteristics
Unless otherwise noted: -20°C < T
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 to ground.
2. These limits define the range of operation for which the part will meet specification.
3. Within the supply range of 2.7 and 3.6 V, the device operates as a fully calibrated linear accelerometer. Beyond these supply limits the device
4. The device can measure both + and – acceleration. With no input acceleration the output is at midsupply. For positive acceleration the output
5. The digital input pin has an internal pull-down resistance to prevent inadvertent self-test initiation due to external board level leakages.
6. Time for the output to reach 90% of its final value after a self-test is initiated.
7. Preserves phase margin (60°) to guarantee output amplifier stability.
8. A measure of the device’s ability to reject an acceleration applied 90° from the true axis of sensitivity.
