8.2.2 Detailed Design Procedure

The TMP103 devices must be placed in close proximity to the heat source that must be monitored, with a proper layout for good thermal coupling. This placement ensures that temperature changes are captured within the shortest possible time interval. To maintain accuracy in applications that require air or surface temperature measurement, take care to isolate the package and leads from ambient air temperature. The TMP103 device is a very low-power device and generates very low noise on the supply bus. Applying an RC filter to the V⁺ pin of the TMP103 device can further reduce any noise that the TMP103 device might propagate to other components.
