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

{ΔAVCC/ΔVDAC12_xOUT}.

4. VREF is applied externally. The internal reference is not used.
