In fact, the minimum recommended voltage is ±10V, and the minimum output swing at ±15V and 10k load(!) is ±12V, a whole 6V less than the supply voltage. It would appear that your simulation does not at all capture the specifics of an LM741. Even a rail-to-rail opamp could not conjure -5V from a V- of 0V. | |
