NOTES) 1. Zero offset error is the difference between 000000000000 and the converted output for zero input
voltage (VSS).
2. Top offset error is the difference between 111111111111 and the converted output for top input
voltage (AVREF).
3. When AVREF is lower than 2.7V, the ADC resolution is worse.
