TEMPERATURE ACCURACY VS. SUPPLY
The temperature accuracy specifications are guaranteed for
voltage supplies of 3 V and 5.5 V only. Figure 16 gives the
typical performance characteristics of a large sample of parts
over the full voltage range of 2.7 V to 5.5 V. Figure 17 gives the
typical performance characteristics of one part over the full
voltage range of 2.7 V to 5.5 V.

TYPICAL TEMPERATURE ERROR GRAPH
Figure 18 shows the typical temperature error plots for one
device with V
Figure 19 shows a histogram of the temperature error at
ambient temperature (40°C) over approximately 6,000 units.
Figure 19 shows that over 70% of the AD7414/AD7415 devices
tested have a temperature error within ±0.3°C.
