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 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
