Some people would say that's real sloppy. A precision analog circuit would like its ground to be protected from glitches caused by other parts. And if the primary is precision analog then some people might think of the protecting to be the primary purpose. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
