SBOS740A May 2017 – May 2019 TMP116
The TMP116 operates on a power-supply range from 1.9 V to 5.5 V. The device is trimmed for operation at a 3.3-V supply, but can measure temperature accurately in the full supply range. A power-supply bypass capacitor is required, which must be placed as close as possible to the device. A recommended value for this supply bypass capacitor is 100 nF. Applications with noisy or high-impedance power supplies may require additional decoupling capacitors to reject power-supply noise.
The TMP116 is a very low-power device and generates low noise on the supply bus. Applying an RC filter to the V+ pin of the device can further reduce any noise that the TMP116 might propagate to other components. RF in Figure 44 must be less than 0.5 kΩ and CF must be at least 100 nF. Take care that the V+ pin voltage is not less than 1.9 V. The package thermal pad is not connected to the device ground and should be left unsoldered for the best measurement accuracy. If the thermal pad is soldered it must be left floating or connected to ground.
