INA226-Q1: How to convert actual current value?

Part Number: INA226-Q1

Hi team,

my customer would like to know if they read INA226-Q1 internal register value then they want to know how to calculate actual current or voltage value?

Please advise

Ps. if we have convert excel tool will be preferred.


  • Hello Paul,

    Here is how you convert the data for the shunt, bus, and current values:

    Shunt Voltage: Multiply the register value by the shunt LSB value of 2.5µV

    Bus Voltage: Multiply the register value by the bus LSB value of 1.25mV

    Current: Multiply the register value by your chosen current LSB. See section 7.5 of the datasheet to see how to calculate your current LSB and Calibration register value. Here is a screenshot for convenience:
