POWER DISSIPATION
Figure 74 through Figure 78 detail the power dissipation of the
AD9785/AD9787/AD9788 under a variety of operating conditions.
All of the graphs are taken with data being supplied to both the
I and Q channels. The power consumption of the device does
not vary significantly with changes in the modulation mode or
analog output frequency. Graphs of the total power dissipation
are shown along with the power dissipation of the DVDD18,
DVDD33, and CVDD18 supplies.
The power dissipation of the AVDD33 supply rail is independent
of the digital operating mode and sample rate. The current drawn
from the AVDD33 supply rail is typically 51 mA (182 mW) when
the full-scale current of the I and Q DACs is set to the nominal
value of 20 mA. Changing the full-scale current directly impacts
the supply current drawn from the AVDD33 rail. For example,
if the full-scale current of the I DAC and the Q DAC is changed
to 10 mA each, the AVDD33 supply current drops to 31 mA.
