Obviously, if you put in 12V it won’t be able to produce 24V on a 15V supply, so be reasonable. Non-inverting amplifier example ...

Because the inverting input is at virtual ground, the output of the inverting op amp is V OUT = −IR2 = −V IN R2/R1. Thus, the gain of the inverting op-amp circuit is −R2/R1.

Fig. 2: Unity-Gain Follower (Non-Inverting) With the invention of the transistor in 1947 (see our related Milestone article “The Transistor Portable Radio”), a parallel development program of tube and ...

2. In an inverting and single non-inverting input op-amp summer, R1-R3 interact to some extent (Equation 2). Equation 2 is still manageable: R1-R3 are interactive, but not terrible to deal with. 3.

(If this op amp were operated in a buffer configuration, it would have a phase margin of 43 degrees.) If the op amp were used in an inverting configuration with a gain of one, K would be 0.5 or -6dB ...

In my previous article on common op-amp circuits, I mentioned that operational amplifiers were used for analog computing, where analog circuits simulated the behavior of complex systems. That article ...
