AI Absolute Accuracy (Warranted)

Table 2. AI Absolute Accuracy
Nominal Range Positive Full Scale (V)	Nominal Range Negative Full Scale (V)	Residual Gain Error (ppm of Reading)	Residual Offset Error (ppm of Range)	Offset Tempco (ppm of Range/°C)	Random Noise, σ (μVrms)	Absolute Accuracy at Full Scale (μV)
10	-10	48	13	21	315	1,660
5	-5	55	13	21	157	870
2	-2	55	13	24	64	350
1	-1	65	17	27	38	190
0.5	-0.5	68	17	34	27	100
0.2	-0.2	95	27	55	21	53
0.1	-0.1	108	45	90	17	33

Note Absolute Accuracy at Full Scale is determined using the following assumptions:

TempChangeFromLastExternalCal = 10 °C
TempChangeFromLastInternalCal = 1 °C
NumberOfReadings = 10,000
CoverageFactor = 3 σ

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

Gain tempco	13 ppm/°C
Reference tempco	1 ppm/°C
INL error	60 ppm of range

AI Absolute Accuracy Equation

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

GainError = ResidualGainError + GainTempco · (TempChangeFromLastInternalCal) + ReferenceTempco · (TempChangeFromLastExternalCal)
OffsetError = ResidualOffsetError + OffsetTempco · (TempChangeFromLastInternalCal) + INLError
NoiseUncertainty =
$\frac{Random Noise \cdot 3}{\sqrt{10, 000}}$
for a coverage factor of 3 σ and averaging 10,000 points.

AI Absolute Accuracy Example

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

GainError: 48 ppm + 13 ppm · 1 + 1 ppm · 10 = 71 ppm
OffsetError: 13 ppm + 21 ppm · 1 + 60 ppm = 94 ppm
NoiseUncertainty:
$\frac{315 µ V \cdot 3}{\sqrt{10, 000}}$
= 9.4 µV
AbsoluteAccuracy: 10 V · (GainError) + 10 V · (OffsetError) + NoiseUncertainty = 1,660 µV
