SNIS218A September 2019 – April 2020 TMP390-Q1
The low supply current and wide supply range of the TMP390-Q1 allow the device to be powered from many sources. VDDIO must always be lower than or equal to VDD + 0.3 V.
Power supply bypassing is strongly recommended by adding a 0.1-µF capacitor from VDD to GND. In noisy environments, TI recommends to add a filter with 0.1-µF capacitor and 100-Ω resistor between external supply and VDD to limit the power supply noise.
