May we know INA226 is direct mode or linear mode for register's value? Customer would like to double check for FW reading. Thanks a lot!!

Hi Ann Lien,
INA226 register value conversion takes place in a different format than the example you provided.
Its register values are proportional to the parameters (current/voltage/power) being reported. A multiplier would be applied to the register values in order to translate into physical readings in ampere, volt or watt.
For example, to convert Bus voltage from the Bus Voltage register, simply multiply the decimal register value by 1.25mV. The resulting value would be Bus voltage in mV.
