The series resistor chain has 3.3 minus 1.2 then 2.1 volts
So you calculate the current , resistors 1.32 kohm in all
And then determine voltage accross a resistor
Simulation and actual results are matching that is the reason i posted to understand.
If we go by your way, it is not even matching anywhere.
If you do so, Its shows 1.9V.

Bjtpower_magic, next time, it would be more producent to provide the calculation that you are not agreeing, no one is able to realize the exact point you undestand as wrong. BTW, some answers crossed the edge, so the thread will be locked for while.

Just so as not to leave the thread unanswered, the OpAmp selected has a pair of differential power bus, while in the simulation it was fed with an asymmetrical Vcc/GND source, so this could very likely be impacting the result.
