RMS NOISE AND RESOLUTION
The tables in this section show the rms noise, peak-to-peak
noise, effective resolution, and noise-free (peak-to-peak) resolu-
tion of the AD7195 for various output data rates and gain settings,
with chop disabled and chop enabled for the sinc4 and sinc3
filters. The numbers given are for the bipolar input range with
the external 5 V reference. These numbers are typical and are
generated with a differential input voltage of 0 V when the ADC
is continuously converting on a single channel. It is important
to note that the effective resolution is calculated using the rms
noise, whereas the peak-to-peak resolution is calculated based
on peak-to-peak noise. The peak-to-peak resolution represents
the resolution for which there is no code flicker.
