We are using a THS4520 Differential Amplifier to convert from a bi-polar single ended signal to a differential 0-5 Volt signal in a signal conditioning module (SCM). We are powering it with a single +5V supply. There is a specification on the datasheet that says that the input voltage can never exceed +/- Vs, but all of the supplies used in the specification tables are referring to a system with split +/- supplies. My question is this: In a system with a single +5V power supply, what is the maximum allowable range for the V+ and V- input signals on the amplifier?
