I am creating an Op-Amp Integrator circuit in Multisim. It seems to work for sinusoidal voltage inputs, square wave inputs, etc but when I connect it to a DC source the output voltage (channel A in the diagram below) just immediately goes to -11V. Based on the integrator equation (-1/RC)*integral(v(t)dt), the output voltage should be equal to -0.4t (-0.4 volts per second). I have tried using a bunch of different values for R, C and Vin. The Op-Amp is a 741 Op- Amp. Thank you for any advice.
