Table 2. Operating Characteristics
Unless otherwise noted:
1. For a loaded output, the measurements are observed after an RC filter consisting of an internal 32 kΩ resistor and an external 3.3 nF capacitor
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 4g mode.
5. The device can measure both + and – acceleration. With no input acceleration the output is at midsupply. For positive acceleration the output
6. For optimal 0g offset performance, adhere to AN3484 and AN3447.
7. The response time between 10% of full scale V
8. The response time between 10% of full scale Sleep Mode input voltage and 90% of the final operating output voltage.
9. A measure of the device’s ability to reject an acceleration applied 90° from the true axis of sensitivity.
