Demonstration circuit for showing one way to wire a 741 op amp to take an analog input voltage to output a saturated digital signal of the same polarity (non inverting). I use a voltage divider to create a dual polarity variable voltage and a polarity indicator circuit connected to the op amp output to show changing polarity at the output, controlled by the non inverting input.
