AD628 As Level Shifter

Hello,

 

I would like to use an AD628 to sample voltage in a 4-20mA current loop, but with a 0-3.3v output instead of the 0-5v output as depicted in the product datasheet.  I'm not sure about the purpose of the 210k resistor and 2.5v voltage source, and was wondering if you all could provide some insight.

 

Thanks for the help.

Scott
