I am looking at the Anderson Loop as a possible solution for strain measurement and am interested in the 4 sensor circuit on page 13 of the pdf document at https://www.electro-tech-online.com/custompdfs/2003/04/im.pdf. The IC's next to the INA114's are not labelled but I am told, are probably OPA4277's - the quad version of the OPA177. What I don't understand is why these components, which seems to fullfill exactly the same function on each separate gauge circuit, utilises different pins [13,12/9,10/2,3/6,5].
I would be grateful if somebody could explain.
Thankyou
