Thanks for the suggestion, but I only need to sample at 100Hz and the table doesn't show a Tad value for that slow of a sampling rate. That table has always confused me. Would anyone know why the slower the sampling rate, the higher the minimum Tad time requirement? If I understand correctly, Tad represents the amount of time that it takes to convert one bit. Shouldn't it take the same amount of time to convert the bits, regardless of how fast you're sampling? -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
