NOTES:
2. The full-scale transition at xINP is the difference between the signal input voltage that causes the 4094 to 4095 transition and the
measured reference voltage Vref(RT).
3. The zero-scale transition at xINP is the difference between the signal input voltage that causes the 0 to 1 transition and the reference
voltage Vref(RB).
4. Differential nonlinearity (DNL) is the difference between the measured value between any two adjacent codes and the ideal 1 LSB
value.
5. Integral nonlinearity (INL) is the maximum deviation of the output from the ideal straight line between zero and the full-scale value.
