9.3 Power Supply Recommendations

The TMP411-Q1 operates with a power supply range of 2.7V to 5.5V, while the TMP411D-Q1 power supply range of 1.62V to 5.5V. The device is optimized for operation at a 3.3V supply, but measures temperature accurately in the full supply range. TI recommends using a power supply bypass capacitor. Place the capacitor as close as possible to the supply and ground pins of the device. 0.1µF is a typical value for the supply bypass capacitor. Applications with noisy or high-impedance power supplies can require additional decoupling capacitors to reject power-supply noise.
