ADA4092-4 differential input voltage

Please let me know about overvoltage protection (OVP) of ADA4092-4.


Datasheet P. 6 tabel5 absolute maximum rating says below.
Input Voltage: Refer to the Input Overvoltage Protection section
Differential Input Voltage: ±VSY


What is the difference between input voltage and differential input voltage ?
Our customer asks if above means that OVP does not work when differential signal input is used,
because customer uses ADA4092-4 in below condition.


Operated condition
5V single supply
Input signa: 2.5V +-2.5V differential input

(-10~+10V overvoltage protection is needed )
