NOTES: 1. No load at the output pin, DAC12_0 or DAC12_1, 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.
