AD8290 : need some inquiries.

Hi,

 

I'm using the AD8290 to monitor the temperature given by a Pt100 RTD.

 

I have a couple of question regarding this device :

 

1 - On page 3 of the datasheet related to the specs, the INPUT row specifies the Input Voltage Range min & max values. Should it be understood as the differential Input Voltage Range values?

 

2 - On page 18, I have some trouble interpreting the calculation results printed in table 10 about the Input Voltage Min and Max, and the Output Voltage Min and Max.

Computing myself the values with the data given in table 8, 9, and the beginning of table 10 didn't gave me the same results.

So what would be the literal equations leading to the correct calculus?

 

Michel
