I'm starting the hardware design for the ADAU1467, and I have a few questions:
First Question - I plan to use 5V main power supply, and I plan to minimize current consumption to minimum as much as I can. To do so, I plan to use switch mode power supplies (unlike the evaluation board that both 3.3V, and 1,2V rails are supplied using LDOs)
Is the following power supply design is acceptable? (any suggestions for how to improve the design would be welcomed)
Second Question - Are there any software configurations that needs to be set when using external 1.2V supply, as above?
