1. Better performance could be achieved in restricted V
2. Based on characterization, not tested in production.
3. If IRROFF is set to V
ADC accuracy vs. negative injection current: injecting a negative current on any analog input
pins should be avoided as this significantly reduces the accuracy of the conversion being
performed on another analog input. It is recommended to add a Schottky diode (pin to
ground) to analog pins which may potentially inject negative currents.
Any positive injection current within the limits specified for I

EO = Offset Error: deviation between the first actual transition and the first ideal one.
EG = Gain Error: deviation between the last ideal transition and the last actual one.
ED = Differential Linearity Error: maximum deviation between actual steps and the ideal one.
EL = Integral Linearity Error: maximum deviation between any actual transition and the end point
correlation line.
