AD7712: power supply

If he wants to input +/-10V single-ended signal to AIN2. What power supply
should he use? Single 5V, single 10V or +/-5V? I can not find very clear
statement in the datasheet.

 

For an analog input of +/-10V on the channel, a supply of +/-5V can be used.
For an analog input of 0-10V, a supply of 0-5V can be used.
