Figure 40. ADC accuracy characteristics

1. Example of an actual transfer curve

2. The ideal transfer curve

3. End point correlation line

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.

Figure 41. Typical application with ADC

1. Legend: RAIN = external resistance, CAIN = capacitors, Csamp = internal sample and hold capacitor.
