NOTES:
1. For a full-scale output, the reference input voltage can be as high as 1/3 of the maximum output voltage swing (AVCC).
2. The maximum voltage applied at reference input voltage terminal VeREF+ = [AVCC VE(O)] / [3*(1 + EG)].
3. For a full-scale output, the reference input voltage can be as high as the maximum output voltage swing (AVCC).
4. The maximum voltage applied at reference input voltage terminal VeREF+ = [AVCC VE(O)] / (1 + EG).
5. When DAC12IR = 1 and DAC12SREFx = 0 or 1 for both channels, the reference input resistive dividers for each DAC are in parallel
reducing the reference input resistance.
