Hello , I am trying to simulate a simple opamp circuit with Linear's LT Spice simulator. The circuit is simply a single supply opamp, the minus input connected to 0.5V and the plus input connect to a 1V sine wave. The output is connected to ground by 1K R.
According to my understanding, I should have at the output a square wave. However, I am getting only a dc value. Can someone check my ''design''
I have the LT Spice asc file:
