If you inspect the LM comparator, you will notice metal wires that stick out. Okay, thanks for your input. Low input offset voltage: 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. In the OP, there was no specification of exactly what the levels were, and for all one datasheeh the inputs were so close together that datashret comparator was responding to thermal drifts.
Production processing does not necessarily include. Datasheets for the LM can be downloaded here: 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. Setting the internal pull up did not work unfortunately. I’ve got the LMN’s in the mail, and they show the same scenario. Low input offset current: Marketing proposal for customer feedback. On all other products, production processing does not necessarily include testing of all parameters.
I have two inputs for my LMP comparator https: 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 wired-AND relationships.
Not Recommended for New Design. One thing I am concerned about, is that the marking on the comparator isn’t the same as in the datasheet. I will order some extra indeed, unfortunately I only have the one at hand. No commitment taken to datashset Proposal: 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.
Product is in volume production Evaluation: 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. Datxsheet measures voltages at two different points and compares the difference in quantity of voltage.
Distributor Name Region Stock Min. If you enable the internal pull-up in the Arduino it should work as that will pull the signal high when the Lm339p is not conducting.
Having the comparator been placed in reverse, should I expect it to be broken or is there possibly another cause to my problem? What does precision mean for an op amp? The problem is your inputs. If the first point has a higher voltage than the second point, the switch is turned on.
Did my comparator break?

Instead, try a circuit like this simulate this circuit — Schematic created using CircuitLab. When building your own robot on a solderless breadboard, one of the components of the robot will be its brains.
Sign up using Facebook. If you connected it and powered it thinking pin 5 was pin 1 then you very well could have killed it. I got the comparator working! Daatasheet Engineering samples available Preview: Selectors Simulators and Models.
I will keep this question open and check whether a new IC will fix the problem. To add some info, originally I was using photodiodes to compare the outputs of two of them and send the result to the Arduino. Putting a 1K resistor between Vcc and output did the trick. These datashewt called pins.

L,393p commitment taken to design or produce NRND: I guess that’s what you’re saying, I forgot to mention that.

I’ve added a bit to the original post. WhatRoughBeast 49k 2 28 This way gives well-defined input levels, and the operation of the comparator is clearly defined. The readings almost always return 1, but periodically return 0.
