100pF up to 10k will not degrade the performance) (see
Figures 14, 15).
In cases where large bypass capacitors are required
on the reference inputs (CREF > 0.01F) full-scale and
linearity errors are proportional to the value of the refer-
ence resistance. Every ohm of reference resistance pro-
duces a full-scale error of approximately 0.5ppm (while
operating in simultaneous 50Hz/60Hz mode) (see Figures
16 and 17). If the input common mode voltage is equal to
the reference common mode voltage, a linearity error of
approximately 0.67ppm per 100
Ω of reference resistance
results (see Figure 18). In applications where the input
and reference common mode voltages are different, the
errorsincrease.A1Vdifferenceinbetweencommonmode
input and common mode reference results in a 6.7ppm
INL error for every 100
Ω of reference resistance.
