    hi could some one help choosing the wright comparator for making a circuit that when the inverting + input exceeds the -input the output goes high (Vcc) and when it is less the output goes low (GND).. the circuit i know exactly how it should be put using the LM339 the output goes or 6V more or less...or else 0V ...and the Vcc is 12v....i used lm339 , lm 393 and even lm311 and all gave me same result...
    thanks stefan
