    Hello Everybody

    I am using CA3140 as a comparator and I need pulses of 5 volt at its output. I am getting pulses at the output but they go in negative range as well and also the output is higher than 5 volts, if anybody can help me out that what kind of settings I have to made to get 5 volts output pulses. The datasheet of CA3140 can be seen through following link.

    Thanks everyone

    @wayneh this is how I am connecting my circuit and giving a signal of 2 Volts at the non inverting input and connected a voltage divider circuit at Inverting input with 5 Volts and supply voltages are + and - 5Volts
