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
specifications.
3. PSRR = 20*log{∆AV_CC/∆V_{DAC12_xOUT}}.
4. V_REF is applied externally. The internal reference is not used.
