Im trying to simulate the lm693 comparator in electronic work bench.

With a Vref=Vcc = 5V
R1 = 100K
R2 = 2K
R3 = 8 K

When Vin reaches 4.92125 V this will trigger a low output

When Vin reaches 2.95276 V this will trigger a high output

I was expecting a change in output when I changed the sine wave amplitude on the function generator. However no matter what amplitude changes I make to the function gnerator my output is the same.

WHy isn't my simulation working?
