Sensitivity is the smallest voltage change that can be detected. It is a function of noise.
For example, on the 10 V range, the absolute accuracy at full scale is as follows:
GainError = 60 ppm + 13 ppm · 1 + 1 ppm · 10
GainError = 83 ppm
OffsetError = 20 ppm + 21 ppm · 1 + 60 ppm
OffsetError = 101 ppm
275 μV ⋅ 3NoiseUncertainty = ------------------------NoiseUncertainty = 83 μV
100
AbsoluteAccuracy = 10 V · (GainError) + 10 V · (OffsetError) + NoiseUncertainty AbsoluteAccuracy = 1920 μV
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 = 100
CoverageFactor = 3 σ
AbsoluteAccuracy = Reading · (GainError) + Range · (OffsetError) + NoiseUncertainty
GainError = ResidualAIGainError + GainTempco · (TempChangeFromLastInternalCal) + ReferenceTempco · (TempChangeFromLastExternalCal)
OffsetError = ResidualAIOffsetError + OffsetTempco · (TempChangeFromLastInternalCal) + INL_Error
RandomNoise ⋅ 3
NoiseUncertainty = ----------------------------------------For a coverage factor of 3 σ and averaging 100 points.

Stresses beyond those listed under Input voltage protection may cause permanent damage to the device.
Performance can be dependent on bus latency and volume of bus activity.
The digital subsystem does not have its own dedicated internal timing engine. Therefore, a sample clock must be provided
from another subsystem on the device or an external source.

In other sections of this document, RTSI refers to RTSI <0..7> for PCI/PCIe devices or PXI_TRIG <0..7> for PXI/PXIe
devices.
Some motherboards reserve the x16 slot for graphics use. For PCI Express guidelines, refer to ni.com/pciexpress.
If you are using a USB M Series device in full-speed mode, device performance will be lower and you will not be able to
achieve maximum sampling/update rates.
Operating on a full-speed bus may result in lower high-speed full-speed performance.
