Is it required to use all the ports on the comparator for it to work?

Current drain is independent of the supply voltage.

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 least 1.

Marketing proposal for customer feedback. ST Code of Conduct Blog. The LM can accept inputs down to the negative rail and a bit beyond.

I have 5v from the Arduino running to Vcc of the comparator and the ground of the comparator running to the Arduino ground.

Home – IC Supply – Link. Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. The discussion on the LM comparator chip, which is frequently used by robot builders, is directed to those who are interested in building a light sensing robot, but is still useful for all who wish to incorporate a voltage comparator chip in their robot.

No commitment taken to produce Proposal: I have two inputs for my LMP comparator https: I guess that’s what you’re saying, I forgot to mention that. The problem is your inputs. Update; IC isn’t damaged.

Support Center Video Center. Writing with the digital ports, high and low, alternated by a second, I got the comparator to play nice. I believe it to be the side of the small circular indentation now. Just ordered some xatasheet LM’s. Who We Are Management. The readings almost always return 1, but periodically return 0.

Information on the LM Comparator Chip for Use in Robotic Circuits

If you enable the internal pull-up in the Arduino it should work as that will pull the signal high when the LM is not conducting. This makes the LM suitable with a 9 V battery, since this l,393p has a voltage range of approximately 5 V to 10 V.

I figure it must be that the IC is damaged. Setting the internal pull up did not work unfortunately.

L3m93p from split power supplies is also datashset. I accidentally mistook delay for being seconds, but it is instead milliseconds. Now to get it to work with my photodiodes. 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. Key Features Wide single-supply voltage range or dual supplies: 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.

Media Subscription Media Contacts.

If the first point has a higher voltage than the second point, the switch is turned on. The datasheet provided for the LM states that it has an optimal voltage range of 2 V to 36 V. Product is under characterization. If you have another one, double check your connections and input voltages, and drop it in.

Instead, daatsheet a circuit like this simulate this circuit — Schematic created using CircuitLab.
