Design Notes
Place the TMP117 close to the heat source to ensure accurate temperature measurement. Follow the layout guidelines in the datasheet: place decoupling capacitors within 5 mm of the VCC pin, and keep I2C pull-up resistors at least 10 mm away to minimize noise. Use a solid ground plane under the sensor to improve thermal coupling.
The TMP117 operates from 1.8 V to 5.5 V. Use a 0.1 µF ceramic capacitor close to the VCC pin for decoupling. In noisy environments, a 1 µF capacitor may be added. Ensure the supply voltage is stable to maintain measurement accuracy.
Avoid placing the TMP117 near heat-generating components or in direct airflow, as this can affect accuracy. When soldering, follow the recommended reflow profile to prevent damage. The ALERT pin is open-drain and requires a pull-up resistor. Do not exceed the absolute maximum ratings for supply voltage and temperature.
