9 Power Supply Recommendations

The TMP139 operates with dual supply pins. The supply VDDIO is used for the bus interface and operates in the

range of 0.95 V to 1.05 V. The pin VDDSPD is used as the supply for the core and operates in the range of 1.7 V

to 1.98 V. A power-supply bypass capacitor is required for precision and stability. Place these power-supply

capacitors as close to the supply and ground pins of the device as possible. A typical value of these supply

bypass capacitor is 0.01 µF. Applications with noisy or high-impedance power supplies can require a bigger

bypass capacitor to reject power-supply noise.
