Place the TMP102 device in close proximity to the heat source that must be monitored, with a proper layout for good thermal coupling. This placement verifies that temperature changes are captured within the shortest possible time interval. To maintain accuracy in applications that require air or surface temperature measurement, care must be taken to isolate the package and leads from ambient air temperature. A thermally-conductive adhesive is helpful in achieving accurate surface temperature measurement.

The TMP102 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 TMP102 device can further reduce any noise that the TMP102 device can propagate to other components. R_(F) in Figure 7-2 must be less than 5 kΩ and C_(F) must be greater than 10 nF.
