1. For a loaded output, the measurements are observed after an RC filter consisting of an internal 32 k

Ω resistor and an external 3.3 nF capacitor

(recommended as a minimum to filter clock noise) on the analog output for each axis and a 0.1

μF capacitor on V

bandwidth is determined by the Capacitor added on the output. f = 1/2

the minimum to filter out internal clock noise.

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 1.5g mode.

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

6. For optimal 0g offset performance, adhere to AN3484 and AN3447

7.Product Performance will not exceed this minimum level, however measurement over time will not be equal to time zero measurements for

this specific parameter.

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

10. A measure of the device’s ability to reject an acceleration applied 90° from the true axis of sensitivity.
