What about high precision ADCs? I'm working on a design using ADE7753 power monitor chips (16-bit ADCs) , and their own app note (AN564) shows a ferrite isolating analog ground, and a 10R resistor isolating AVdd. _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
