Temperature Coefficient vs. Operating
Temperature Range for a
1 LSB Maximum Error
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-

age temperature coefficient to keep the conversion
error to less than 1 LSB, as a function of the operating

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.
