Second, the increase in clock frequency will increase
proportionally the amount of sampling charge trans-
ferred through the input and the reference pins. If large
external input and/or reference capacitors (CIN, CREF)
are used, the previous section provides formulae for
evaluating the effect of the source resistance upon the
converter performance for any value of fEOSC. If small
external input and/or reference capacitors (CIN, CREF) are
used, the effect of the external source resistance upon
the LTC2483 typical performance can be inferred from
Figures 9, 10, 11 and 12 in which the horizontal axis is
scaled by 307200/fEOSC.

Third, an increase in the frequency of the external oscil-
lator above 1MHz (a more than 3+ increase in the output
data rate) will start to decrease the effectiveness of the
internalautocalibrationcircuits.Thiswillresultinaprogres-
sive degradation in the converter accuracy and linearity.
Typicalmeasuredperformancecurvesforoutputdatarates
up to 100 readings per second are shown in Figures 16
to 23. In order to obtain the highest possible level of
accuracy from this converter at output data rates above
20 readings per second, the user is advised to maximize
the power supply voltage used and to limit the maximum
ambient operating temperature. In certain circumstances,
a reduction of the differential reference voltage may
be beneficial.
