10. Preserves phase margin (60°) to guarantee output amplifier stability.
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
13. The Status pin output latches high if a Low Voltage Detection or Clock Frequency failure occurs, or the EPROM parity changes to odd. The Status pin
11. A measure of the device's ability to reject an acceleration applied 90° from the true axis of sensitivity.
1. For a loaded output the measurements are observed after an RC filter consisting of a 1 k
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
4. The device can measure both + and – acceleration. With no input acceleration the output is at midsupply. For positive acceleration the output will
5. The device is calibrated at 20g.
6. At clock frequency 70 kHz.
7. The digital input pin has an internal pull-down current source to prevent inadvertent self test initiation due to external board level leakages.
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.
