1. Conditions: AV
2. The differential non-linearity (DL
3. The ADC is monotonic, there are no missing codes.
4. The integral non-linearity (IL
5. The offset error (OS
6. The gain error (G
7. The absolute voltage error (A
8. This should be considered when both analog and digital signals are input simultaneously to Port 5. Parameter is guaranteed by design.
