OUTPUT NOISE AND RESOLUTION SPECIFICATIONS
AD7798
Table 5 shows the AD7798 output rms noise for some update
rates and gain settings. The numbers given are for the bipolar
input range with a 2.5 V reference. These numbers are typical
and are generated with a differential input voltage of 0 V. Table 6
shows the effective resolution, and the output peak-to-peak
resolution is shown in parentheses. It is important to note that
the effective resolution is calculated using the rms noise, whereas
the peak-to-peak resolution is based on the peak-to-peak noise.
The peak-to-peak resolution represents the resolution for which
there is no code flicker. These numbers are typical and are
rounded to the nearest LSB.
