AD7323 - Input and Supply Range

Hello all,

 

We have an analog input signal which ranges from -3V up to 11V.  So we were planning to use the AD7323 with +/-12 analog input range and with supply voltages of 15V(Vdd) and -5V(Vss) as well as having Vref to be 3V to enable the +/-12V range. 

 

With the +/-12V range do we need to have supply voltages equal to or greater than this or do we simply need supply voltages that are equal to or greater than the input signal?

 

The Data Sheet for AD7323 can be seen here: http://www.analog.com/static/imported-files/data_sheets/AD7323.pdf

 

Thanks,

Cameron
