4 / 10 page 4 Accuracy Maximum errors over limited temperature spans, with VS = +5V, are listed by device grade in the following tables. The tables reflect the worst-case linearities, which invariably occur at the extremities of the specified temperature range. The trimming conditions for the data in the tables are shown in Figure 2 and Figure 4. All errors listed in the tables are ±oC. For example, if ±1oC maximum error is required over the 25oC to 75oC range (i.e., lowest temperature of 25oC and span of 50oC), then the trimming of a J-grade device, using the single-trim circuit (Figure 2), will result in output having the required accuracy over the stated range. An I-grade device with two trims (Figure 4) will have less than ±0.2oC error. If the requirement is for less than ±1.4oC maximum error, from -25oC to 75oC (100oC span from -25oC), it can be satisfied by an I-grade device with two trims. FIGURE 5D.
