@IRstuff, well if the device's input (J201) is +- 10V, isn't Vin gonna be +- 1000V given that there are two amplification stages between J201 and Vin ?
I am studying the schematics of an analog isolator with variable gain (SIM 984 from SRS0, the isolator is bipolar and can handle positive and negative voltages.
In the isolation part of the schematics (see picture below), the author uses two voltage references circled in red.
