1. Typical data is based on TA=25°C, Vdd=5V
2. Monotonicity and No Missing Codes are guaranteed by design.
3. Refer to Figure 162. for the definition of these parameters.

ET=Total Unadjusted Error: maximum deviation
between the actual and the ideal transfer curves.
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.
