NOTES:
1. For a loaded output the measurements are observed after an RC filter consisting of a 1 k
resistor and a 0.1
μ
F capacitor to ground.
2. These limits define the range of operation for which the part will meet specification.
3. Within the supply range of 4.75 and 5.25 volts, 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. Thedevicecanmeasureboth+and
acceleration.Withnoinputaccelerationtheoutputisatmidsupply.Forpositiveaccelerationtheoutput
will increase above V
DD
/2 and for negative acceleration the output will decrease below V
DD
/2.
5. Sensitivity limits apply to 0 Hz acceleration.
6. At clock frequency
34 kHz.
7. Thedigital inputpin has an internalpull--down currentsource toprevent inadvertentself testinitiation dueto externalboard levelleakages.
8. Time for the output to reach 90% of its final value after a self--test is initiated.
9. Time for amplifiers to recover after an acceleration signal causing them to saturate.
10. Preserves phase margin (60
°
) to guarantee output amplifier stability.
11. A measure of the device’s ability to reject an acceleration applied 90
°
from the true axis of sensitivity.
12. The Status pin output is not valid following power--up until at least one rising edge has been applied to the self--test pin. The Status pin is
high whenever the self--test input is high.
13. The Status pin output latches high if the EPROM parity changes to odd. The Status pin can be reset by a rising edge on self--test, unless
a fault condition continues to exist.
