9 Power Supply Recommendations

The LM95214 operates on a power-supply range from 3.0 V to 3.6 V. A power-supply bypass capacitor is required, which much be placed as close as possible to the supply and ground pins of the device. A typical 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.
