Larger values of reference capacitors (CREF > 0.01F) may
be required as reference filters in certain configurations.
Such capacitors will average the reference sampling charge
and the external source resistance will see a quasi con-
stant reference differential impedance. When FO = LOW
(internal oscillator and 50Hz/60Hz notch), the typical
differential reference resistance is 1.4M
which will gen-
erate a gain error of approximately 1LSB full scale for each
40
of source resistance driving REF+ or REF–. When FO
is driven by an external oscillator with a frequency fEOSC
(external conversion clock operation), the typical differen-
tial reference resistance is 0.20 1012/fEOSC and each
ohm of source resistance drving REF+ or REF– will result
in 1.54 10–7 fEOSCLSB gain error at full scale. The effect

of the source resistance on the two reference pins is
additive with respect to this gain error. The typical +FS and
–FS errors for various combinations of source resistance
seen by the REF+ and REF– pins and external capacitance
CREF connected to these pins are shown in Figures 19, 20,
21 and 22.
In addition to this gain error, the converter INL perfor-
mance is degraded by the reference source impedance.
When FO = LOW (internal oscillator and 50Hz/60Hz notch),
every 1000
of source resistance driving REF+ or REF–
translates into about 1LSB additional INL error. When FO
is driven by an external oscillator with a frequency fEOSC,
