Akijinn They helped a lot. You need to add a pull-up resistor of about 10k between the output pin and your positive supply rail. My wiring diagram looks similar to this picture I created in LTspice.

I will look into your question. Sign up using Facebook. Comparator help LmN Ask Question. Sign up using Email and Password. Also, thanks for the 10K resistor idea that got the voltage down to what I was hoping to see.

Email Required, but never shown. One more question thought please? I mistakenly thought the inverted its output. Can anyone help me come up with ideas to try and get this working? However, when I check the output the resulting voltage is 0v. After testing the pull up resistor, I am left wondering when I invert the inputs I do not get 0v like I was expecting.

The LM has an open collector output so it can datasheeet actively drive a positive voltage. I am using a LMN to learn about comparators. The horn is about 15 ohms. If you have a new question relating to a car horn, you should ask it separately.

After I get my desired voltage out of datasbeet Comparator, how do I stabilize it so that I can use it on a load? You need a pullup resistor. Thank you for pointing this out and I will go back over the datasheet to get a better understanding of how to read it.
