Hi there, I'm trying to change a 0-3.3V input to a +-3.3V output with a comparator that has a reference of 1.65 but I can seem to be able to make it work. Does anyone know what I'm doing wrong?

Хай! С вашей схемой у меня не получилось, взял отсюда: https://monitorbank.ru/komparatory-napryazheniya/
Надеюсь, правильно вас понял...
Удачи!

Hi GabrielM. and tipa,
The first thing to do is to provide the proper negative supply voltage to LM311. There are two ways to do this:
Next, the circuit should be rewired so that the LM311 can function as intended. There are four options available to achieve the objective:
The most suitable configuration depends on the application circuit.
Again, I don't have the (Desktop) application version of Multisim. I am only a Free Subscription user of Multisim Live so the LM311 is not available to me. I just edited the circuit image that was posted, you can try building these modified circuits in Multisim and provide feedback if they work as expected.
Best regards,

Спасибо, дорогой! Как всегда толково и подробно и понятно. Вышла новая версия 14.3
Можешь поставить себе.
