INA233: Understanding INA233 READ_IN units

Part Number: INA233

Hello, I am using several INA233 on my custom board to monitor various power rails. I have programmed the MFR_CALIBRATION register and now reading the READ_IN register to get the measured current. 

Here's my question, after I read the register READ_IN am I correct in multiplying it by my CURRENT_LBS value?

Last, what is the units of my answer?

Looking my my results I would think the units would be milliAmps?

Thank you

Joe

  • Hello Joe,

    Correct, the value in READ_IN should be multiplied by the CURRENT_LSB. The following result from that would be in Amps. Here is a section from the datasheet that may help clear things up for you:
