Figure 2 shows an example for isolating the ADC power supply from the I/O supply (EVDD) and ground. Note that in this
power supply the 10
resistor is replaced by a 0 resistor. This will reduce the IR drop into the ADC, limiting additional gain
error.

Figure 3 shows an example for bypassing the internal core digital power supply for the MPU. This bypass should be applied to
as many IVDD signals as routing allows. Each one should be placed as close to the ball as possible.

Figure 4 shows an example for bypassing the external pad ring digital power supply for the MPU. This bypass should be applied
to as many EVDD signals as routing allows. Each one should be placed as close to the ball as possible.
