±0.5°C Accurate, 10-Bit Digital Temperature Sensors in SOT-23

Analog Devices 

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.

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.
