AD977A Maximum reading voltage

Question

I am using AD977A/AD976A on my PCB, how much voltage it can sense at the input terminal? As it is coming with an internal reference voltage of 2.5V, can we collect the analogue voltage signal at the input of amplitude 2.5 V - 5V?

Hi, 
 As per datasheet. The AD977/AD977A is specified to operate with six full-scale analog input ranges. Connections required for each of the three analog inputs, R1IN, R2IN and R3IN, and the resulting full-scale ranges, are shown in Table I and Table II. 
 
 Thanks,
