inverse sinc filter, both DACs, and the on-board comparator

are enabled. Basic configuration means the output scaling

multipliers, the inverse sinc filter, the control DAC, and the

on-board comparator are disabled.

Figure 60 shows the approximate current consumed by each of

the four functions.
