PRIMARY AND AUXILIARY ADC NOISE PERFORMANCE
Tables X, XI, and XII show the output rms noise in mV 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 com-
plete with an ADC noise evaluation tool. This tool can be easily
used with the evaluation board to see these figures from silicon.
