AD7903 - can it do +/-5v differential input?

Question

Dear ADI, 
 
 I have two a low-impedance source of two (2) differential analog channels/voltages (X and Y) that are both +/-5v (ie: +/-10v SE equivalent) and I would like to sample them with the AD7903 - am I able to just wire those signals directly into the AD7903 as follows without the need of any drivers ? :- 
 
 +X (-5v..+5v) -> IN1+ 
 -X (-5v..+5v) -> IN1- 
 
 +Y (-5v..+5v) -> IN2+ 
 -Y (-5v..+5v) -> IN2- 
 
 Thanks very much! 
 Cheers, 
 Rodney

Thanks very much, Achim! That is very helpful!)

Hi RodneyDavies , 
 Achim is correct. The absolute input voltage, INx+ and INx-, is -0.1V to Vref+0.1V. You will need to condition your -5V input to a voltage level acceptable by the ADC. Connecting the -5V input directly should be avoided as it may damage the device.
