I notice that there is no ADC ref pin on these devices what is the best low cost solution to get a good 5V ref.
Is it just to use a good 5V regulator or are there any other methods?2003-07-16 10:21 PM
It can be done using good voltage regulator. There is one application note available, downloadable from the same site i.e AN1636 ''UNDERSTANDING AND MINIMISING ADC CONVERSION
ERRORS''. Hope this would help.2003-07-18 02:14 AM
Effectively on some devices Vdda is internally connected to Vdd and Vssa to Vss.
You will find advises on some dedicated application notes downloadable on this site!
