Hi, i'm currently building a comparator circuit using a lm324n op amp.
The problem is, i get an output even when the voltage at the negative terminal is greater than at the positive terminal. I have 6.2v at the positive and 6.5v at the negative. I'm just wondering how accurate these op amps are, because i've simulated the circuit on multisim and it works fine.
