DAC Average Current Consumption
DAC D, E, F: The average current consumed by each DAC is the DAC output current as determined by RSET2/VREF (see Appendix 8).
DAC A, B, C: In normal power mode the average current consumed by each DAC is the DAC output current as determined by RSET1
(see Appendix 8).
In Low Power Mode the average current consumed by each DAC is approximately half the DAC output current as determined by RSET1.
Consult AN-551 for detailed information on ADV7172/ADV7173 power management.
