---|---|---|---|---|---
10| -10| 48| 34| 230| 1769
5| -5| 55| 35| 130| 929

Gain tempco: 10 ppm/°C
Reference tempco: 1 ppm/°C
Residual offset error: 20 ppm of range
INL error: 13 ppm of range1

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

AI Absolute Accuracy Equation

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

Temp Change From Last ExternalCal = 10 °C
SampleRate ≥ 10 MS/s
Temp Change From LastInternal Cal = 1 °C
number _of readings = 10,000
Coverage Factor = 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 = 230 μV ⋅ 3 10, 000 = 6.9 µV AbsoluteAccuracy = 10 V · (GainError) + 10 V · (OffsetError) + NoiseUncertainty = 1707 µV
