Can Op-Amp (LM358) works as an integrator without dual mode power supply?
Can an Op-Amp work as an integrator without dual mode power supply?

Sure it can, the opamp doesn't care and also it doesn't know.

Here are two integrator circuits, on the left with a symmetrical supply. On the right using a single supply. Note how I created a 5 V "virtual ground" as a "working point" for the opamp.

Do note that only the left circuit can output positive and negative voltages.

The right circuit's output signal will always be positive.

But both are integrators.
