How non-inverting amplifier works
The input drives the non-inverting terminal. Feedback from the output through R2 and R1 sets a gain of one plus their ratio. The output has the same polarity as the input.
Ideal DC equations assume negative feedback and operation within the supply rails. The guest uses a generic op-amp model; finite gain, input loading, output current and saturation can change the simulated result.
