The A/D conversion result never decreases with an increase in the input voltage, and has no missing
codes.
These parameters are characterized by similarity, but are not tested in manufacturing.
These parameters are characterized, but are tested at 20 ksps only.
Injection currents > | 0 | can affect the ADC results by approximately 4-6 counts.
