POWER DISSIPATION
Figure 91 to Figure 99 show the power dissipation of the 1.8 V and 3.3 V digital and clock supplies in single DAC mode and dual DAC
mode. 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.
