Nominal Range Positive Full Scale	Nominal Range Negative Full Scale	Residual Gain Error (ppm of Reading)	Offset Tempco (ppm of Range/°C)	Random Noise, σ (μVrms)	Absolute Accuracy at Full Scale (μV)

5	-5	55	35	130	929
2	-2	55	37	66	380

Note For more information about absolute accuracy at full scale, refer to the AI Absolute Accuracy Example section.

Gain tempco 10 ppm/°C

Reference tempco	1 ppm/°C
Residual offset error	20 ppm of range
INL error	13 ppm of range^{^[1]}

Note Accuracies listed are valid for up to two years from the device external calibration.

AI Absolute Accuracy Equation

AbsoluteAccuracy = Reading · (GainError) + Range · (OffsetError) + NoiseUncertainty

GainError = ResidualAIGainError + GainTempco · (TempChangeFromLastInternalCal)

+ ReferenceTempco · (TempChangeFromLastExternalCal)

OffsetError = ResidualAIOffsetError + OffsetTempco ·

(TempChangeFromLastInternalCal) + INLError

Random Noise ⋅ 3

NoiseUncertainty = for a coverage factor of 3 σ and averaging

100 points.

AI Absolute Accuracy Example

Absolute accuracy at full scale on the analog input channels is determined using the following assumptions:

• TempChangeFromLastExternalCal = 10 °C

• SampleRate ≥ 10 MS/s

• TempChangeFromLastInternalCal = 1 °C

• number_of_readings = 10,000

• CoverageFactor = 3 σ

For example, on the 10 V range, the absolute accuracy at full scale is as follows:

GainError = 48 ppm + 10 ppm · 1 + 1 ppm · 10 = 68 ppm

OffsetError = 20 ppm + 34 ppm ·1 + 92 ppm = 102 ppm

Noise Uncertainty = = 6.9 µV

AbsoluteAccuracy = 10 V · (GainError) + 10 V · (OffsetError) + NoiseUncertainty = 1707 µV
