INTERNAL REFERENCE
Table 8 shows the output rms noise of the AD7792/AD7793 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, with the output peak-to-peak (p-p)
resolution given in parentheses for the AD7793 and AD7792,
respectively. It is important to note that the effective resolution
is calculated using the rms noise, while the p-p resolution is
calculated based on p-p noise. The p-p resolution represents the
resolution for which there is no code flicker. These numbers are
typical and are rounded to the nearest LSB.
