Part Number: INA220

Tool/software:

1. Will this design work, kindly confirm.

2. Is one high frequency 0.1uf cap is enough for Vs power pin, right?

3. We are trying to measure 0.8V on VBus pin and Gnd, will this work?

    Hi Vishnu,

    Yes your schematic looks good. The datasheet specs provide a abs max range of -0.3V to 26V on the Vbus pin, so 0.8V should work fine.

    Yes that is sufficient.

    I don't see a shunt resistor in the schematic, I assume it fits the specifications mentioned in the datasheet.

    Best,
