ADC Sample Rates
The MMA955xL platform supports the following sample rates:
•
488.28 frames per second (fps)
•
244.14 fps
•
122.07 fps
•
61.04 fps
•
30.52 fps
•
15.26 fps
•
7.63 fps
•
3.81 fps
In addition to the previous list, additional sample rates are available with the MMA9559L device.
•
3906.25 fps
•
1953.13 fps
•
976.56 fps
•
1.91 fps
•
0.95 fps
•
0.48 fps
•
0.24 fps
Note:
The highest rates have a restriction in terms of ADC resolution selection as time available for data conversion is much
reduced.
