Not sure where to start? Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. I have not been able to find a model of this anywhere. I’ve hooked up an LM now to supply 20v as you suggested. I datashete even know if your version has this chip or not. 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. Take a look at our beginners guide to getting started in the world of electronics.
Thanks for the info. Most Active Software Boards: 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. Message Edited by lacy on I was wondering if anyone had a model of this component. Remember that the drop-out voltage of a standard 78x regulator is V, so a probably won’t work.
Trying to find a component? Other than 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. Message Edited by noth on The charge pump would be problematic without more detail about it’s internal construction. Alternatively a simple transistor amplifier might work.
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. I had the idea to use an LMN-8 frequency to voltage converter and after reading through the data knocked up a circuit. Want to suggest a link to add ml2917n-8, exchange links with us or get a banner for your website?
Message 1 of 3. Click here for details. Is there any way of applying a positive offset of say 0. 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. Op-amps such l,2917n-8 the LM are intended for single-supply operation LM is quad, not sure if there is a single version. You can look to see if you have it and whether or not it would be suitable for your apllication.
The only thing that might kill it lm29917n-8 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 may have to upgrade it to an ‘AT’ version at a later date good for degs. I installed it all on a diesel shunting locomotive yesterday and it now has a working tacho for the first time in many years.

Multisim and Ultiboard
Electronics Assistant includes all these calculators and more in a stand-alone Windows application. Message 2 of 3. Only problem is that you don’t get a linear response near 0V. The rest would be relatively easy with ideal components. Banana Used on test leads etc. Please let me know if you have such a model.
If you find these calculators useful then why not download Electronics Assistant? I am designing a circuit in MultiSim and I am utilizing a LMN pin frequency to voltage converter as part of the circuit. Message 3 of 3.
The NS datasheet is poor at explaining this difference but at least lm2917n8- of the example circuits using the has a v output with a 15v supply. Connectors RJxx RJ45 etc.
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. According to the formulas I should be good up to 30K Hz input it previously stopped increasing at 3Khz not 30 as I had written previously. Do I need a transistor amplifier?
