INA228: Current conversion result

Part Number: INA228

Hi Team，

I would like to double check that if the value of the CURRENT register is the ADC conversion result of the voltage across the sampling resistor? Thanks.

Regards，

    Hello Hailiang,

    The "VSHUNT" register (0x04) is the register for the ADC conversion result for the voltage across the shunt resistor. The "CURRENT" register (0x07) gives you current through the shunt resistor based on the value in the "VSHUNT" register and the value in the "SHUNT_CAL" register (0x02).

    Regards,
