I'm replacing a stolen PCM4222EVM adc with a PCM4202EVM adc but they left my + -15V, 5V triple-output linear power supply. However, I just discovered that there is a difference in powering the PCM4202EVM in that it also requires an extra DIGITAL 5V supply, so 4 separate power supplies: + - 15V, 5V & 5V Digital.
Being a dolt, can I just solder a wire to my 5V supply and run it to the digital header or do I need to do some kind of decoupling with a capacitor setup? Also, what would I do with the grounds?
I may replace the triple-linear with a triple-switching supply if that makes any difference with adding the 5V digital. Both would supply adequate current for the dual 5V draw btw.
