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 28 through 35, inclusive. 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 refer-
ence voltage may be beneficial.
