NOTES:
1. This is the peak-to-peak value that is not exceeded 95% of the time.
2. This parameter is measured with an external reference having a temperature coefficient of less than 0.01 ppm/oC.
3. The magnitude of the difference between the worst case step of adjacent counts and the ideal step.
4. Rollover error is the difference between the absolute values of the conversion for 2V and -2V.
