Selection of unit gain instrumentation amplifier

Category: Datasheet/Specs
Product Number: MAX4195, AD8251, AD8250

I have a sensor that puts out two signals, one 0-10V and another 10-0V.

I would like to subtract these two signals, so that I get a signal that is +/- 10V, which I can then connect to an input channel in my DAQ.

To this subtraction, I would like to use an instrumentation amplifier with gain = 1.

I was first looking at the MA4195 which has a fixed gain = 1. But then I realized that it's V_IN cannot be the 10V that I need.

So I am thinking of using the AD8251 or AD8250.

Is this a good approach?

Thank you.
