8-BIT ADC CHARACTERISTICS (Cont’d)
ADC Accuracy
Figure 101. ADC Accuracy Characteristics
Notes:
1. ADC Accuracy vs. Negative Injection Current:
For IINJ-=0.8mA, the typical leakage induced inside the die is 1.6A and the effect on the ADC accuracy is a loss of 1 LSB
for each 10K
increase of the external analog source impedance. This effect on the ADC accuracy has been observed
under worst-case conditions for injection:
- negative injection
- injection to an Input with analog capability, adjacent to the enabled Analog Input
-at5VVDD supply, and worst case temperature.
2. Data based on characterization results with TA=25°C.
3. Data based on characterization results over the whole temperature range, monitored in production.

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.
