(1)
This is specified by design and characterization; it is not tested in production.
(2)
In CMOS mode, the DRVDD current scales with the sampling frequency, the load capacitance on output pins, input frequency and the
supply voltage (see Figure 81 and CMOS power dissipation in application section).
(3)
The maximum DRVDD current depends on the actual load capacitance on the digital output lines. Note that the maximum
recommended load capacitance on each digital output line is 10 pF.
