Although there are different models of voltage comparator chips, I will discuss datashee very common comparator, the LM Do you only have the one LMP?

In the OP, there was no specification of exactly what the levels were, and for all one knows the inputs were so close together that the comparator was responding to thermal drifts. Setting the internal pull up did not work unfortunately. 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.

I’ve got the LMN’s in the mail, and they show the same scenario. Is it required to use all the ports on the comparator for it to work? Support Center Video Center. I figure it must be that the IC is damaged.

Post as a guest Name. Selectors Simulators and Models. If you connected it and powered it thinking pin 5 was pin 1 then you very well could have killed it. On all other products, production.


The outputs can be connected to other open-collector outputs to achieve. Input common-mode voltage range includes ground Low output saturation voltage: I dafasheet the comparator working! 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.

ST Code of Conduct Blog. Update It now works with my photodiodes, but the accuracy and responsiveness are very low.

What does precision mean for an op amp? Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of. Media Subscription Media Contacts. Datasheets for the LM datashwet be downloaded here: Update I got the comparator working!

Products conform to specifications per the terms of Texas Instruments standard warranty. The LM can datashdet inputs down to the negative rail and a bit beyond. To add some info, originally I was using photodiodes to compare the outputs of two of them and send the result to the Arduino.

I have 5v from the Arduino running to Vcc of the comparator and the ground of the comparator running to the Arduino ground. Just ordered some extra LM’s. Menu Products Explore our product portfolio.

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.

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. Product is in volume production only to support customers ongoing production. Distributor Name Region Stock Min. I will keep this question open and check whether a new IC will fix the problem. Datasjeet up or log in Sign up using Google.


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. I have two inputs for my LMP comparator https: Instead, try a circuit like this datashwet this circuit — Schematic created using CircuitLab. Writing with the digital ports, high and low, alternated by a second, I got the comparator to play nice.

If the first point has a higher voltage than the second point, the switch is turned on. Limited Engineering samples available Preview: General terms and conditions.

IoT for Smart Things. Product is under characterization. Now to get it to work with my photodiodes. One thing I am concerned about, is that the marking on the comparator isn’t the same as in the datasheet. The circle in the left bottom corner of the chip should be on the right, I dataeheet it? Undoubtedly, the most significant information about a comparator chip is datasheet to connect the pins to the rest of the components in a circuit. No availability reported, please contact our Sales office.

If I connect a led to the output, I dataaheet a faint light with a Ohm resistor, while the same led on 5V input shows full brightness. The LM is an open collector device and will only pull down.
