AI Absolute Accuracy

Table 1. AI Absolute Accuracy

10 -10 114 35 252 2,688
5 -5 120 36 134 1,379
2 -2 120 42 71 564

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

Gain tempco

Reference tempco

5 ppm/°C

Residual offset error

15 ppm of range

INL error

46 ppm of range

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 = ResidualGainError + GainTempco · (TempChangeFromLastInternalCal) + ReferenceTempco · (TempChangeFromLastExternalCal)
  • OffsetError = ResidualOffsetError + OffsetTempco · (TempChangeFromLastInternalCal) + INLError
  • NoiseUncertainty =
    RandomNoise310,000
    for a coverage factor of 3 σ and averaging 10,000 points.

AI Absolute Accuracy Example

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

  • TempChangeFromLastExternalCal = 10 °C
  • 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 = 114 ppm + 8 ppm · 1 + 5 ppm · 10 = 172 ppm
  • OffsetError = 15 ppm + 35 ppm ·1 + 46 ppm = 96 ppm
  • Noise Uncertainty =
    252μV310,000
    = 7.6 µV
  • AbsoluteAccuracy = 10 V · (GainError) + 10 V · (OffsetError) + NoiseUncertainty = 2688 µV
