refer to the attachment, in what application do we use the follower configuration? i just thought that configuration is used to test the output dynamic range. please give some comment.
Re: how to configure an fully differential opamp as follower
If you connect + output to - input and - output to + input then you have no more inputs to your circuit and there will be stability issues both AC and DC with a non ideal amp. You can use unity gain adjusted fully differential opamps (instrumentation amplifiers) if you only need a differential buffer or sacrifice the high input impedance of the differential opamp and use resistors.
