Update I got the comparator working! 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. Instead, try a circuit like this. 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.

Just ordered some extra LM’s. ST Analog cards High-performance operational amplifiers and comparators, the best choice for longevity, robustness and performance. This way gives well-defined input levels, and the operation of the comparator is clearly defined. Key Features Wide single-supply voltage range or dual supplies: Update; IC isn’t damaged. One thing I am concerned about, is that the marking on the comparator isn’t the same as in the datasheet.

Please contact our sales support datassheet information on specific devices. I am using input 1 of the comparator, having checked that I am lk393p the correct input and output ports.

Why is the other device datadheet Update Just ordered some extra LM’s. 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. I have 5v from the Arduino running to Vcc of the comparator and the ground of the comparator running to the Arduino ground.


No commitment taken to design or produce NRND: The datasheet provided for the LM states that it has an optimal voltage range of 2 V to 36 V. Introduction to comparators, their parameters and basic applications.

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. What does precision mean for an op amp? The LM can accept inputs down to the negative rail and a bit beyond. WhatRoughBeast 49k 2 28 Limited Engineering samples available Preview: Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of.

These are called pins. I’ve tried wiring up the digital ports to the input pins of the comparator, but that shows no decent results. If the first point has a higher l3m93p than the second point, the switch is turned on. I have two inputs for my LMP comparator https: When building your own robot on a solderless breadboard, one of the components of the robot will be its brains. 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.


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.

To add some info, originally I was using photodiodes to compare the outputs of two of them and send the lm93p to the Arduino. Computers and Peripherals Data Center.

The readings almost always return 1, but periodically return 0. KevinWhite – Sure, but that’s not the point. Product is in volume production only to support customers ongoing production. On all other products, production processing does not necessarily include testing of all parameters. Product is in volume production Evaluation: I placed a 1K resistor between Vcc and output. I ordered new ones and the same datashwet apply.

I guess that’s what you’re saying, I forgot dagasheet mention that. Support Center Video Center. Left side of the breadboard was used for another version. Products conform to specifications per the terms of Texas Instruments.

Datasheets for the LM can be downloaded here: Product is in volume production 0. However, if the first point has a lower voltage than the second point, the switch is turned off.

I see that in the picture it is actually the wrong way around probably too. Putting a 1K resistor between Vcc and output did the datasjeet. Terry Ligard is a fourth year mechanical engineering student at the University of Alberta.
