So for a project I needed just a simple comparator circuit to turn on a fan when the temperature was above a certain value. I thought no problem, I'll just use a simple LM311 circuit. Well when I connected it, I would only get 1.6v on the output no matter what i did with the inverting or non-inverting inputs. I thought this was weird so I build another circuit using it just as a buffer powered by 5v and 2.5v at the non-inverting input. These values are within the specs and it still did the same thing with the 1.6v. Thinking my chip may be bad, I tried two other LM311 chips and it did the same thing. Any idea what could be going on here?
Thanks for your time
