PRODUCTION DATA.
To achieve the expected results when measuring temperature with an integrated circuit temperature sensor like the LM73-Q1, it is important to understand that the sensor measures its own die temperature. For the LM73-Q1, the best thermal path between the die and the outside world is through the LM73-Q1's pins. In the SOT-23 package, all the pins on the LM73-Q1 will have an equal effect on the die temperature. Because the pins represent a good thermal path to the LM73-Q1 die, the LM73-Q1 will provide an accurate measurement of the temperature of the printed circuit board on which it is mounted.
