OUTPUT NOISE AND RESOLUTION SPECIFICATIONS
EXTERNAL REFERENCE
Table 5 shows the output rms noise of the AD7785 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 shows the effective resolution, with the
output peak-to-peak (p-p) resolution shown in parentheses. 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.
