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. Made some new observations. In a general lm39p, an analog voltage comparator chip is ,m393p a small voltmeter with integrated switches. Terry has several months of experience building electromechanical transporters. Products conform to specifications per the terms of Texas Instruments.
If your Arduino is reading both states, 0 and 1, your comparator may be OK.
The readings almost always return 1, dataeheet periodically return 0. WhatRoughBeast 49k 2 28 No commitment taken to produce Proposal: I’ve got the LMN’s in the mail, and they show the same scenario.
Not Recommended for New Design.
Although there are different models of voltage comparator chips, I will discuss a very common comparator, the LM Putting a 1K resistor between Vcc and output did the trick. Who We Are Management. Sign up using Facebook.
arduino – Did my comparator break? – Electrical Engineering Stack Exchange
The outputs can be connected to other open-collector outputs to achieve wired-AND relationships. Terry Ligard is a fourth year mechanical engineering student at the University of Alberta. Buy Lm3393p Add to cart. Update I got the comparator working! No availability reported, please contact our Sales office. 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.
Km393p thing I am concerned about, is that the marking on the comparator isn’t the same as in the datasheet. Low input offset current: Writing with the digital ports, high and low, alternated by a second, I got the comparator to play nice.

When building your own robot on a solderless breadboard, one of the components of the robot will be its brains. Selectors Simulators and Models. It measures voltages at two different points and compares the difference in quantity lm393 voltage. Free Sample Add to cart.

Product is in volume production only to support customers ongoing production. Okay, thanks for your input. The 1K resistor is not necessary and you could connect it directly to the Arduino but lm393 shouldn’t hurt operation either so you can leave it there. The other comparator should be configured so that the output is high-impedance.
I’ve added a bit to the original post. No commitment taken to design or produce NRND: Product is under characterization.
Update It now works with my photodiodes, but the accuracy and responsiveness are very low. ST Analog cards High-performance operational amplifiers and comparators, the best l3m93p for longevity, robustness and performance. Support Center Video Center.

Update; IC isn’t damaged. I ordered new ones and the same results apply.
Please be aware that an important notice concerning availability, datasheett warranty, and use in critical applications of. I placed a 1K resistor between Vcc and output.
I can’t see the pin 1 marker in the photo but you are right in that is often a small dimple next to pin 1.
