#80563 - RE: How good is this scheme?
Responding to: ???'s previous message
Prahlad said:
If I am right in the PCB of above circuit the AGND and DGND might be meeting under the ADC MCP3201. Thus this is the star ground point. And the power connector too should be located at this place... am I right??


Yes. Think about why I have drawn digital ground lines in red. Because these ground lines are noisy, spiky and dirty. Do never connect anything analogeous to these red lines! The only point where analog ground is allowed to meet digital ground is the star ground point at ADC, where analog and digital ground pins are connected to each other.
