INA240: Differences in detailed model numbers of INA240

Conor

Part Number: INA240

Tool/software:

Hi ,

I am considering the INA240 series A1: 20V/V, A2: 50V/V, and A3: 100V/V.

Is it correct to understand that the circuit configuration of the above model numbers is only different in the resistors that determine the gain?

Are the internal OpAmp circuit configuration and PWM Rejection configuration all the same?

Thanks,

Conor

    Conor,

    Thanks for the question and using the E2E forum.

    Yes, the only differences in the devices is the resistors determining their gain. For a couple of specs, there will be a slight difference depending on the gain version, but all of the devices will function the same.

    Please let us know if you have any other questions.
