The TMP107-Q1 device operates with a power supply in the range of 1.7 V to 5.5 V. The device is optimized for operation at a 3.3-V supply, but measures temperature accurately for the full supply range. For best performance, use a 0.1-µF power-supply bypass capacitor. Place the bypass capacitor as close as possible to the supply and ground pins of the device. Applications with noisy or high-impedance power supplies may require additional bypass capacitors to reject power-supply noise.
