Circuit Note
method were approximately the same as the value obtained by
multiplying the rms value by 6.6.
The values obtained from the sample set are in LSBs, so they
must be converted into voltage, where 1 LSB = 0.596 µV for a
5 V reference.
If desired, the results of several sample sets can be averaged to
get a more accurate measurement.
Noise-free code resolution is calculated from the peak-to-peak
noise as described previously in this circuit note.
