OUTPUT NOISE AND RESOLUTION SPECIFICATIONS
EXTERNAL REFERENCE
Table 5 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 an external 2.5 V reference.
These numbers are typical and are generated with a differential
input voltage of 0 V. Table 6 and Table 7 show the effective
resolution, with the output peak-to-peak (p-p) resolution
shown 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 based on the 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.
