AD7606 Transfer Characteristics Question

Hi,

 

I setup AD7606 pin8 that is RANGE to high, It means the ADC Vin Range is +-10V; Now when Vin =DC 5V, DSP processor  read data from AD7606 is 33292, When Vin =DC3.3V, DSP processor  read data from AD7606 is 22328; It's not consistent with transfer characteristics;

So could you tell me how to get the Vin real value base on the data which read  from AD7606?

 

Thanks a lot

Kevin
