Web19 de jun. de 2016 · if the op amp has an open loop gain of 1 million, since the output is -10 volts, the voltage difference at the input will be about 10 uV. In fact, it is the very small input voltage which allows an approximate gain formula G = − R 2 R 1 to be usefully correct, since the - input can be considered to be held at ground.
