5 Improve Temperature Accuracy

The TMP61 shows the methods needed to achieve high accuracy in How to Achieve ±1°C Accuracy or Better Across Temperature With Low-Cost TMP6x Linear Thermistors, which includes:

• How to perform the single-point offset correction to remove the tolerance errors from TMP6x and other components in the thermistor biasing circuit.
• How to implement oversampling and software filtering to reduce noise and increase measurement precision.

Besides these methods, additional system level considerations can also be implemented to improve temperature measurement accuracy.
