Is it still good to Split AGND and DGND?
I have been reading the Aplication Note "Grounding Data Converters and Solving the Mystery of AGND and DGND", and the Autors recommend to split Agnd and DGND but other Voices ( z.b. Altium Academy) say it is hard to get good results.
I'm trying to make a nA Transienten measurement system, a 4 Layer board. I use 2 components witch are mixed ( Adc ADS8681 and a Dac ), the Amplifier is a TIA build with a LMC6001( i know not the perfect part but yea, i have them on hand). Any Dokuments were I can read about it?
