Hello, in AD698 spec, I found offset voltage calculate formula. according to this formula, I get the R4 value I wanted.

But when I soldering R4 in my PCB board. there is still have some AD698 no any offset voltage output, the R2 output voltage no any change.

 

Could you help me analyze it? Thanks!
