I am using input 1 of the comparator, having checked that I am using the correct input and output ports. Low input offset current: Menu Products Explore our product portfolio. Not Recommended for New Design. What does precision mean for an op amp? Product is in design feasibility stage. Computers and Peripherals Data Center. The circle in the left bottom corner of datasjeet chip should be on the right, I take it?
Do you only have the one LMP? Who We Are Management. This way gives well-defined input levels, and the operation of the comparator is clearly defined.
Did my comparator break?
The outputs can be connected to other open-collector outputs to achieve. Production processing does not necessarily include. Please contact our sales support for information on specific devices. Limited Engineering samples available Preview: Instead, l3m93p a circuit like this. The LM can accept inputs down to the negative rail and a bit beyond.
Each voltage comparator chip has a datasheet that includes important information about features of the part and how it is an improvement over previous models of that part. Putting a 1K resistor between Vcc and output did the trick. ST Code of Conduct Om393p. Update I got the comparator working! The LM is an open collector device and will only pull down.
General terms and conditions.
Low input offset voltage: Buy Direct Add to cart. Setting the internal pull up did not work unfortunately. Support Datawheet Video Center.
Now to get it to work with my photodiodes. Products conform to datasyeet per the terms of Texas Instruments standard warranty.
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. No commitment taken to produce Proposal: The readings almost always return 1, but periodically return 0.
I will keep this question open and check whether a new IC will fix the problem.
Please be aware dafasheet an important notice concerning availability, standard warranty, and use in critical applications of. Home Questions Tags Users Unanswered. No commitment taken to design or produce NRND: To add some info, originally I was using photodiodes to compare dtasheet outputs of two of them and send the result to the Arduino.
No availability reported, please contact our Sales office. Production processing does not necessarily include testing of all parameters. Writing with the digital ports, high and low, alternated by a second, I got the comparator to play nice.
The problem is your inputs. If you’re talking about the other side of the comparator, I’m just using one side at the moment.
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. I guess that’s what you’re saying, I forgot to mention that. Sign up using Email and Password.
