Internal Reference
Table 8 shows the AD7794/AD7795 rms noise for some of the
update rates and gain settings. The numbers given are for the
bipolar input range with the internal 1.17 V reference. These
numbers are typical and are generated with a differential input
voltage of 0 V. Table 9 and Table 10 show the effective resolution
while the output peak-to-peak (p-p) resolution is listed in brackets.
It is important to note that the effective resolution is calculated
using the rms noise while the p-p resolution is calculated based
on peak-to-peak noise. The p-p resolution represents the
resolution for which there is no code flicker. These numbers are
typical and rounded to the nearest LSB.
