Residual offset error

INL error

13 ppm of range[2]2 When within range. At sample rates ≥ 10 MS/s, add an additional 35 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 = ResidualAIGainError + GainTempco · (TempChangeFromLastInternalCal) + ReferenceTempco · (TempChangeFromLastExternalCal)
  • OffsetError = ResidualAIOffsetError + OffsetTempco · (TempChangeFromLastInternalCal) + INLError
  • NoiseUncertainty =
    RandomNoise3100
    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 + (13 + 35) ppm = 102 ppm
  • Noise Uncertainty =
    260μV310,000
    = 7.8 µV
  • AbsoluteAccuracy = 10 V · (GainError) + 10 V · (OffsetError) + NoiseUncertainty = 1708 µV
