  • RE: INA700EVM: Small power measurement with INA700EVM

    Hello Valued Engineer, Using the INA700 to measure 250 uA will be challenging. The device has a rated offset to +/-1.5mA, so you would need to perform a 1-point offset calibration at least and then configure device to measure with long conversion times…

  • RE: INA228: Accuracy of energy measurement

    Hi Mitch, for INA233 or INA232, does it means accuracy better than 10% can be achieved using MCU to calculate energy? Regards, Holger

  • RE: INA260: Common-mode input voltage

    Resolved
    Hi Hannes, This approach should work, and the calculation of power can be done outside the chip as you proposed. In addition, the I2C lines probably need to be level-shifted. Please take a look at INA232 or INA236. Although an external shunt is needed…

  • INA138: Low Cost Solution for measuring Single Phase & Three Phase motor current upto 90A at 500VAC

  • RE: INA2332: Gain of Amplfier B in INA2332 is not achieved.

    Resolved
    Hi Kumar, I think that your calculation issues are. There is Vos specified in INA232, which is up to ±8mV (that is Refer-to-Input or RTI). Since Gain=100V/V, the actual voltage offset set seen at the output is gained in 100. From the simulation, 646.692mV…
