Note 1: The A/D conversion result never decreases with an increase in the input voltage, and has no missing
codes.
2: These parameters are characterized by similarity, but are not tested in manufacturing.
3: These parameters are characterized, but are tested at 20 ksps only.
4: Injection currents > | 0 | can affect the ADC results by approximately 4-6 counts.
