Part Number: INA818
Other Parts Discussed in Thread: INA823

Tool/software:

Hi,

I need a differential to single-ended converter. The input signal has 1MHz bandwidth and a Vcm=1.65V, Vmax 3V, Vmin 0.5V.

The output is connected to an ADC of a uC, power supply 3.3V.

Thanks for support.

Best Regards

    Hello, 

    Is the power supply a single power supply rail of 3.3V? So the INA would be connected to 3.3V and ground? 

    And will you be setting the gain to 1? 

    Regards,
    Ashley

    Hello HD, 

    I would recommend trying the INA823 (INA823 data sheet, product information and support | TI.com) based on your requirements listed above. 

    Please let me know if you have any questions.
    Thank you!

    Regards,
    Ashley

    Hello Ashley,

    ok thanks for information.

    In the meantime I had also found the same product you suggested.

    It seems a good product but it is the only IC in the TI catalog that meets all the requirements. I also tried to see possible alternatives from other manufacturers without success. At this point I have to ask you... is it possible to know the life cycle of this product? How long will it still be produced, just to make some future predictions.

    Kind regards
