ISO124- Output Supply -VS2

Part Number: ISO124

Can we use a Unipolar Supply to the Second Stage of ISO124- The Supply Voltage VS2 Can be +5V & Can -VS2 be Grounded??

The data sheets does not mention this any where. All Examples shows +/-15V applied to +VS2 & -VS2.

Can anyone clarify this and is there any performance related issue in this Configuration??
