In a data converter application, the reference voltage
of the converter must stay within a certain limit to keep
the error in the data converter smaller than the resolu-
tion limit through the operating temperature range.
Figure 1 shows the maximum allowable reference-volt-
age temperature coefficient to keep the conversion
error to less than 1 LSB, as a function of the operating
temperature range (T
resolution as a parameter. The graph assumes the ref-
erence-voltage temperature coefficient as the only
parameter affecting accuracy.
In reality, the absolute static accuracy of a data con-
verter is dependent on the combination of many para-
meters such as integral nonlinearity, differential
nonlinearity, offset error, gain error, as well as voltage-
reference changes.
