LMP circuit – connections, wiring and diagram –

Sep 23, l,311p Antonio, Two different die designs. Hi Ronald, below you can see two trace on pin 2 of U1, the first is with LMP, you can see a spike of In reply to Antonio Giuseppe Marra:. Ok, I found the problem. Content on this site may contain or be subject to specific guidelines or limitations on use. This diagram requires the reader to know the LM pin assignments. But I’d guess it’s about right. Sep 22, Also my potentiometers Poti are used to adjust my Voltage devisions within the circuit to adjust the switching voltage and the hysteresis.

As mentioned you probably should increase the value of the hysteresis pot by a large degree. Is the IC with an open collector the km311p thing for me?

Sep 26, 9: I already got good answers to the components in a previsous thread https: Go to Support forums. All content and materials on this site are provided “as lm3111p.

What do you want to do with the output signal? Lm311p a related question What is a related question? As far as I calculated it, the dimensions of the pots are just so, that I can adjust everything I need. The newly created question will be automatically linked to this question. I want to built an analog signal to TTL ln311p.


Now I am struggling with the next step, which is to integrate the LMP into my circuit. Watch this topic Disable multi-page view. It gives you the correct amount of hyseresis.

This is an open collector output: So the 1k resistor in this case just limits the current. I am not sure how to wire it properly to get the signal I want. Searching for similar topics Its better to replace them with a single pot and a series resistor which also eliminates one adjustment point.

I was not lmm311p to motivate the wrong behavior. Thank you very much in advance! Hi Clemens, thank you for your fast reply. Hi Clemens, you are right. Hello everybody, once again I need your help. Am I right with this? No license, either express or implied, by estoppel or otherwise, is granted by TI.

Since my signal gained from a hot wire signal is quite noisy, I need a rather big hysteresis.
