I have a question about the ADC CHANNEL Specification of the AD7709. The Unit
of the Full Scale Error is different for A Grade and B Grade. Is the value of
0.75 "LSB typ" for the B Grade correct? Or is the correct Unit "% of Full
Scale" for both Grade types?
The units are correct, “% of FSR” was used for the A grade as if you used
“LSBs” it would be considerably higher than the B grade. Essentially this is
just to show a “better” number from the users point of view for the A grade.
