APPLICATIO S I FOR ATIO
input and/or reference capacitors (C
previous section provides formulae for evaluating the
effect of the source resistance upon the converter perfor-
mance for any value of f
or reference capacitors (C
the external source resistance upon the LTC2436-1 typical
performance can be inferred from Figures 14, 15, 19 and
20 in which the horizontal axis is scaled by 139,800/f

Third, an increase in the frequency of the external oscilla-
tor above 460800Hz (a more than 3 increase in the output
data rate) will start to decrease the effectiveness of the
internal autocalibration circuits. This will result in a pro-
gressive degradation in the converter accuracy and linear-
ity. Typical measured performance curves for output data
rates up to 100 readings per second are shown in Fig-
ures 24, 25, 26, 27, 28 and 29. In order to obtain the
