2.3.2.1 System Accuracy

Table 2-1 shows a summary of specified accuracy of the TMP117. However, the designer must also consider the temperature offset caused by the integration of the device into a design for total system accuracy. A single-point calibration can be performed to negate a consistent temperature offset error in the system. This offset value can be stored in the temperature offset register of the TMP117.

Table 2-1 TMP117 Max Accuracy
TEMPERATURE RANGEMAX ACCURACY °C
-20 °C to 50 °C±0.1 °C
-40 °C to 70°C±0.15 °C
-40 °C to 100°C±0.2 °C
