I was just thinking along similar lines. The 10K load resistor is usually placed close to the op-amps input. See my post and edit just as you were submitting yours ...

Well it needs to be added that the OP-amplifiers are only in older design circuits required. You need a 10nf capacitor as a minimum parallel to the analog input.
Todays low power Analog circuits have the amplifiers build in and are programmable beside 24 bit accuracy.
