Most Active Software Boards: Thanks for the info.

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 datsheet 0 degrees C, I may have to upgrade it to an ‘AT’ version at a later date good for degs. I have not been able to find a model of this anywhere. Message 2 of 3. According to the formulas I lm291n-8 be good up to 30K Hz input it previously stopped increasing at 3Khz not 30 as I had written previously.

Not sure where to start?

National Semiconductor

Only problem is that you don’t get a linear response near 0V. 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 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. You need to experiment to see if this would work though – it’s not something I’ve had the need to try. A simple footprint is easy to make, however, the simulation file s are much more complicated and I do not have to know ln2917n-8 to do this.

Electronics Assistant includes all these calculators and more in a stand-alone Windows application. You can look to see if you have it and whether or not it would be suitable for datadheet apllication.

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. Please let me know if you have such a model. Post any general technical questions here.

Take a look at our beginners guide to getting started in the world of electronics. Trying to find a component? I am designing a circuit in MultiSim and I am utilizing a LMN pin frequency to voltage converter as part of the circuit. 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.

Kittmaster’s Component Database http: Message Edited by noth on 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. Message Edited by lacy on Message 1 of 3. The rest would be relatively easy with ideal components.

Multisim and Ultiboard

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 here, exchange links with us or get a banner for your website? Op-amps such as the LM are intended for single-supply operation LM is quad, not sure if there is a single version. I don’t even know if your version has this chip or not.

Connectors RJxx RJ45 etc. I was wondering if anyone had a model of this component.

LMN-8 Datasheet(PDF) – National Semiconductor (TI)

Banana Used on test leads 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. I’ve hooked up an LM now to supply 20v as you suggested.

Click here for details. Alternatively a simple transistor amplifier might work. Thanks for any help. Simon Carter Electronics http: 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.

Tachometer using LMN-8 – Increasing output – Electronics

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. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. The charge pump would be problematic without more detail about it’s internal construction.
