Click here for details. Message 1 of 3. 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.

I was wondering if anyone had a model of this component. 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.

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.


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. Only problem is that you don’t get a linear response near 0V.

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. Connectors RJxx RJ45 etc. I installed it all on a diesel shunting locomotive yesterday and it now has a working tacho for the first time in many lm2917j-8.

Please let me know if you have such a model.

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. I chose the zener version because it offers output stability with supply rail fluctuations which I will have off an alternator, but I think I will try and limit those with a regulator on the supply instead lk2917n-8.

Message 3 of 3. 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.

Banana Used on test leads etc. I don’t even know if your version has this chip or not. Remember that the drop-out voltage of a standard 78x regulator is V, so a probably won’t 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.


Post any general technical questions here. 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 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 may have to upgrade it to an ‘AT’ version at a later date good for degs. 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. Simon Carter Electronics http: Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type.

Do I need a transistor amplifier? Electronics Assistant includes all these calculators and more in a stand-alone Windows application. I am designing a circuit in MultiSim and I am utilizing a LMN pin frequency to voltage converter as part of the circuit. Not sure where to start?
