6.4.1.1 Voltage Reference and DAC Transfer Function

There are three voltage reference options possible with the AFEx3004W: internal reference, external reference, and the power supply as reference, as shown in Figure 6-4. The DAC transfer function in the voltage-output and comparator modes changes based on the voltage reference selection.
