I am using OP177G for amplifying a strain sensor o/p - 1mV / Kg. I am configuring it as a difference amp as per the picture.
I have practically built this circuit with 1% resistors. The wheat-stone bridge has been constructed from discrete 1% resistors.
My questions are:
Thanks for the informative reply. I have hit the books since your reply and made an excel sheet that incorporates all the details (input offset volts, current, input bias current, Rth of the wheatstone bridge). Waiting to get back to office to test it out.
Please advise on the following:
