  • INA233: Conversion_time_number_of_averages_affect

    TI Thinks Resolved
    Part Number: INA233 Hello, in what examples could different settings of conversion time and different number of averages results in different current measurements of INA233? I used 20 mR resistor which limits the maximum current that could be measured…

  • INA233: transients of up to 38 V

    TI Thinks Resolved
    Part Number: INA233 Hello, in the datasheet of the INA233 is clearly written that voltages over 36 V should not be connected/measured by INA233. But absolute maximum for this amplifier is 40 V. Should I expect that this amplifer should survive rarely…

  • RE: INA233: Is it calibrate the oA ?

    Hey Jerome, Well it seems like the discrepancy and large offset is due to some difference in layout. I would recommend to try isolating the physical layout differences between channels to see what is causing the offset. One example could be disconnecting…
