Tolerance range
Slight variations regarding the calculated values may be within the tolerance
range of the individual component. Two kinds of variations are possible (in
LSB), which are indicated in your hardware manual.
INL
– The integral non-linearity (INL) defines the deviation from the ideal wave
form covering the whole input voltage range.
DNL
– The differential non-linearity (DNL) defines the deviation from the ideal
value of the quantization level.
