PRODUCTION DATA
Refer to the PDF data sheet for device specific package drawings
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.
