These numbers are not production tested, but are guaranteed by design and/or characterization data at production release.
Valid for primary ADC gain setting of PGA = 4 to 64.
Tested at gain range = 4 after initial offset calibration.
Measured with an internal short. A System zero-scale calibration will remove this error.
Measured with an internal short.
These numbers do not include internal reference temperature drift.
