(PDF) LM2917N-8 Datasheet download
Most Active Software Boards: I installed it all on a diesel shunting locomotive yesterday and it now has a working tacho for the first time in many years. I had the idea to use an LMN-8 frequency to voltage converter and after reading through the data knocked up a circuit. Take a look at our beginners guide to getting started in the world of electronics. Want to suggest a link to add lm2971n-8, exchange links with us or get a banner for your website?
The charge pump would be problematic without more detail about it’s internal construction.
Message 1 of 3. The rest would be relatively easy with ideal components. Kittmaster’s Component Database http: The datasheet for this indicates that it is only good for 50hz to 1Khz so I don’t know if this would help any depending on the frequency your working with.
Lm2917nn-8 such as the LM are intended for single-supply operation LM is quad, not sure if there is a single version. Simon Carter Electronics http: The only thing that might kill it now is low temperatures as the LM regulator I had on hand was a ‘T’ version which is only good down to 0 degrees C, I datasjeet have to upgrade it to an ‘AT’ satasheet at a later date good for degs. Trying to find a component? Do I need a transistor amplifier?
I’ve hooked up an LM now to supply 20v as you suggested. If you find these calculators useful then why not download Electronics Assistant?
Connectors RJxx RJ45 etc. I have now read that the output of this chip is limited to this ammount so I need some ideas please on how to boost the output so it can reach 16v DC at around Hz input.
Lm917n-8 don’t even know if your version has this chip or not. I have not been able to find a model of this anywhere.
Remember that the drop-out voltage of a standard 78x regulator is V, so a probably won’t work. Is there any way of applying a positive offset of say 0. A simple footprint is easy to make, however, the simulation file s are much more complicated and I do not have to know how to do this. There is another version of the same chip LMN-8 which doesn’t have this zener so I will try one of those first I think, Vcc will be 24v to the chip so higher output voltage should be possible.
Not sure where to start? Message 3 of 3. Just waiting for my new chip and I’ll report on the results. You can look to see if you have it and whether or not it would be suitable dahasheet your apllication.
If it is just the output voltage that is low you might be OK with an op-amp on a single supply – after all the output doesn’t need to swing negative.
Other lj2917n-8 this, you are left with the only option of creating your own and I don’t know how that could be accomplished with the information contained in the datasheet. Please let me know if you have such a model. You might have to use a lower voltage regulator, a low drop-out type or an LM or similar adjustable regulator set to around 20V or so.
The NS datasheet is poor at explaining this difference but at least one of the example circuits using the has a v output with a 15v supply. You need to experiment to see if this would work though – it’s not something I’ve had the need to try.
Message Edited by noth on Set the split to give at least 16V on the positive side, and a lower negative side hopefully enough to give linear response from the amp down to 0V. I am designing a circuit in MultiSim and I am utilizing a LMN pin frequency to voltage converter as part of the circuit.

Message Edited by lacy on Banana Used on test leads etc. I was wondering if anyone had a model of this component.
Only problem is that you don’t get a linear response near 0V. Click here for details.
