    Residual offset error

    15 ppm of range

    INL error

    spd-note-note
    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 = Random Noise 3 100 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
    • 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 = 252 μ V 3 10 , 000 = 7.6 µV
    • AbsoluteAccuracy = 10 V · (GainError) + 10 V · (OffsetError) + NoiseUncertainty = 2688 µV
