Not sure where to start? I had the idea to use an LMN-8 frequency to voltage converter and after reading through the data knocked up a circuit.

Op-amps such as the LM are intended for single-supply operation LM is quad, not sure if there is a single version. Take a look at our beginners guide to getting started in the world of electronics. Connectors RJxx RJ45 etc. 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.

Kittmaster’s Component Database http: Alternatively a simple transistor amplifier might work. 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.

Do I need a transistor amplifier? I was wondering if anyone had a model of this component. You can look to see if you have it and whether or not it would be suitable for your apllication.

Message 3 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 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 datasheett so it can reach 16v DC at around Hz input. The rest would be relatively easy with ideal components. I installed it all on a diesel shunting locomotive yesterday and it now has a working tacho for the first time in many years. The charge pump would be problematic without more datahseet about it’s internal construction. Just waiting for my new chip and I’ll report on the results.

Is there any way of applying a positive offset of say 0.

I have not been able to find a model of this anywhere. 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. 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. Message 1 of 3. 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 now.

Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. 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 Post any general technical questions here.

Thanks for the info. Banana Used on test leads etc. 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. I am designing a circuit in MultiSim and I am utilizing a LMN pin frequency to voltage converter as part of the circuit.

Thanks for any help. Message 2 of 3. Most Active Software Boards: 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.

Message Edited by lacy on 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. Remember that the drop-out voltage of a standard 78x regulator is V, so a probably won’t work.

Lm917n-8 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. Electronics Assistant includes all these calculators and more in datashest stand-alone Windows application.

I’ve hooked up an LM now to supply 20v as you suggested. Please let me know if you have such a model. Trying to find a component? Only problem is that you don’t get a linear response near 0V.

A simple footprint is easy to make, however, the simulation file s are much more complicated and I do not have to know lm2917b-8 to do this. I don’t even know if your version has this chip or not.
