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-

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 (TMAX - TMIN) with the converter

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.
