Product is in volume production.
I will keep this question open and check whether a new IC will fix the problem. Free Sample Add to cart. Having the comparator been placed in reverse, should I expect it to be broken or is there possibly another cause to my problem?
Now to get it to work with my photodiodes.
Terry has several months of experience building electromechanical transporters. WhatRoughBeast 49k 2 28 Is it required to use all the ports on the comparator for it to work? Update I got the comparator working! Just ordered some extra LM’s. Setting the internal pull up did not work unfortunately.

Made some new observations. I’m not sure of a website or application in which I can draw schematics easily, as I am a beginner to electronics, but I’m willing to sketch a schematic if that’s of use. I accidentally mistook delay for being seconds, but it is instead milliseconds. Key Features Wide single-supply voltage range or dual supplies: I placed a 1K resistor between Vcc and output. 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.

Communications Equipment, Computers and Peripherals. The outputs can be connected to other open-collector datasheeh to achieve wired-AND relationships. Menu Products Explore our product portfolio. Putting a 1K resistor between Vcc and output did the trick.
The LM can accept inputs down to the negative rail and a bit beyond.
The outputs can be connected to other open-collector outputs to achieve. I’ve added a bit to the original post.
Dual Differential Comparator
Update Made some new observations. 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 datashet all who wish to incorporate a voltage comparator chip in their robot. ST Code of Conduct Blog.
Product is in volume production 0. Production processing does not necessarily include testing of all parameters. Sign up or log in Sign up using Google. Writing with the digital ports, high and low, alternated by a second, I got the comparator to play nice. Do you only have the one LMP? The LM, LM, and LM devices consist of two independent low voltage comparators designed specifically to operate from a single supply over a wide range of voltages.
Support Center Complete list and gateway to support services and resource pools. 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. Low input offset voltage: I’ve tried wiring up the digital ports to the input pins of the comparator, but that shows no decent results. Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
Product is in volume production only to support customers ongoing production. The readings almost always return 1, but periodically return 0. The LM is an open collector device and will only pull down. Product is in volume production Evaluation: I guess that’s what you’re saying, I forgot to mention that. The comparator does note it is the LMP however, but I might have mistaken which side was “up”. No availability reported, please contact our Sales office.
Sign up using Email and Password. Product is under characterization. However, if the first point has a lower voltage than the second point, the switch is turned off. Since the LM comparator chip is too small for an indication of the pins to be printed, the datasheet has an illustrated figure, a pinout, which shows the location and function of each pin. Current drain is independent of the supply voltage.
Left side of the breadboard was used for another version. Okay, thanks for your input. General terms and conditions. Did my comparator break? Undoubtedly, the most significant information about a comparator chip is how to connect the pins to the rest of the components in a circuit.
