POWER DISSIPATION
Figure 83 to Figure 91 show the power dissipation of the
1.8 V and 3.3 V digital and clock supplies in single DAC and
dual DAC modes. In addition to this, the power dissipation/
current of the 3.3 V analog supply (mode and speed independent)
in single DAC mode is 102 mW/31 mA. In dual DAC mode,
this is 182 mW/55 mA. When the PLL is enabled, it adds
50 mA/90 mW to the 1.8 V clock supply.
