PRIMARY AND AUXILIARY ADC NOISE
PERFORMANCE
Tables X, XI, and XII show the output rms noise in V and
output peak-to-peak resolution in bits (rounded to the nearest
0.5 LSB) for some typical output update rates on both the primary
and auxiliary ADCs. The numbers are typical and are generated
at a differential input voltage of 0 V. The output update rate is
selected via the Sinc Filter (SF) SFR. It is important to note
that the peak-to-peak resolution figures represent the resolution
for which there will be no code flicker within a six-sigma limit.
The QuickStart Development system PC software comes
complete with an ADC noise evaluation tool. This tool can be
easily used with the evaluation board to see these figures from
silicon.
