Hello all,
I wanted to use one spare op of an OP484 as a comparator. I was wondering about what should care about when using it with positive feedback to have some hysteresis.
I know that the inputs of the 484 can’t be at a different voltage due to their diodes. As long as I use resistors in the inputs of enough value to limit the current to not stress it (for example, 10k, with inputs and supply at 13V), the OP484 will work OK as a comparator? Is there any other problems I should be aware of? I will use it to compare two DC signals.
