NOTES:
1. No load at the output pin assuming that the control bits for the shared pins are set properly.
2. Current into reference terminals not included. If DAC12IR = 1 current flows through the input divider; see Reference Input

× log{ΔAVCC/ΔVDAC12_xOUT}.
4. VREF is applied externally. The internal reference is not used.
