fully differential op-amp

[firsttimedesigning]

so fully differential op-amp has two outputs. but if i want to use it in an integrator, how should i connect? should the - output be connected to the ground? (please see the attached file)

Also, how do i measure the gain, phase and output swing of a fully diff amp? please some me some schematics....

the other terminal should have a similar branch like the input for differential operation

Your connection can work but it's not the best.
The better way is to use another RC connection like the attatched file.

i see...so the negative output should be connected just like the positive output...makes sense now...thx a lot
