Part Number: MSP432E401Y
Other Parts Discussed in Thread: REF6030, REF6033, TPS82130

Hu Guys,

Let me allow to ask something, if i want to use this processor for measuring voltage with the adc, and i want to use a ref voltage 3.0V (ref6030) with 3.3V for VDDA (ref6033). 
Is a very accurate, good and stable 3.3V like REF6033 need for the VDDA or something else is enought( something with noise 5-20mV VPP at 3.3V i made the 3.3V with TPS82130 for the digital part)? 
Well the truth is that i dont know power consumption of the VDDA,and i dont know is the the REF6033 is able to drive the VDDA pin.

I would like to design separate analog and digital part. i know that the 12bit is not too much , but it is good for me but i would like to best for it :)

So the question is in a nut shell.

Should i use precision power supply for vdda, if i add prec voltage ref for vrefa+ ( ref6030 ).
