It measures voltages at two different points and compares the difference in quantity of voltage. The 1K resistor is not necessary and you could connect it directly to the Arduino but it shouldn’t hurt operation either so you can leave it there. I’ve got the LMN’s in the mail, and they show the same scenario. The other comparator should be configured dataxheet that the output is high-impedance.

Left side of the breadboard was used for another version. Operation from dual supplies also is possible as long as the difference between the two supplies is 2 V to 36 V, and V CC is at dafasheet 1. Production processing does not necessarily include testing of all parameters. If you connected it and powered it thinking pin 5 was pin 1 then you very well could have killed it.

If I connect a led to the output, I see a faint light with a Ohm resistor, while the same led on 5V input shows full brightness.

Information on the LM393 Comparator Chip for Use in Robotic Circuits

Sign up using Email and Password. I will keep this question open and check whether a new IC will fix the problem. What does precision mean for an op amp? I’ve added a bit to the original post. Is it required to use all the ports on the comparator for it to work?


Why is the other device floating? Okay, thanks for your input. Update I’ve tried replacing some of the connections to no avail.

To add some info, originally I was using photodiodes to compare the outputs of two of them and send the result to the Arduino. Buy Direct Add to cart.

LMP Datasheet pdf – Low power low offset voltage dual comparator – BayLinear

Undoubtedly, the most significant information about a comparator chip is how to connect the pins to the rest of the components in a circuit. Although there are different models of voltage comparator chips, I will discuss a very common comparator, the LM No commitment taken to design or produce NRND: Terry has several months of experience building electromechanical transporters.

I ordered new ones and the same results apply.

Free Sample Add to cart. Terry Ligard is a fourth year mechanical engineering student at the University of Alberta.

I have 5v from the Arduino running to Vcc of the comparator and the ground of the comparator running to the Arduino ground. Support Center Complete list and gateway to support services and resource pools. Low input offset current: Update Just ordered some extra LM’s. I guess that’s what you’re datasheett, I forgot to mention that.

Having the comparator been placed in reverse, should I expect it to be broken or is there possibly datqsheet cause to my problem? If you’re talking about the other side of the comparator, I’m just using one side at the moment. Email Required, but never shown. When building your own robot on a solderless breadboard, one of the components of the robot will be its brains.

Marketing proposal for customer feedback. If you have another one, double check your connections and input datashet, and drop it in.

Product is under characterization. Since the LM comparator chip is too small for an indication of the pins to be printed, the satasheet has an illustrated figure, a pinout, which shows the location and function of each pin.

I am using input 1 of the comparator, having checked that I am using the correct input and output ports. KevinWhite – Sure, but datasheeet not the point. If your Arduino is reading both states, 0 and 1, your comparator may be OK.

The outputs can be connected to other open-collector outputs to achieve. Setting the internal pull up did not work unfortunately.
