VREF translates into about 2.18 10–6 fEOSCppm addi-
tional INL error. Figure 19 shows the typical INL error due
to the source resistance driving the VREF pin when large
CREF values are used. The user is advised to minimize the
source impedance driving the VREF pin.
In applications where the reference and input common
mode voltages are different, extra errors are introduced.
For every 1V of the reference and input common mode
voltage difference (VREFCM – VINCM) and a 5V reference,
each Ohm of reference source resistance introduces an
extra (VREFCM – VINCM)/(VREF REQ) full-scale gain error,
whichis0.074ppmwhenusinginternaloscillatorand60Hz
mode.Whenusinginternaloscillatorand50Hz/60Hzmode,
the extra full-scale gain error is 0.067ppm. When using
