ADC accuracy vs. negative injection current: Injecting a negative current on any of the
standard (non-robust) 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 standard 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.
