Just waiting for my new chip and I’ll report on the results. 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 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. Op-amps such as the LM are intended for single-supply operation LM is quad, not sure if there is a single version. Connectors RJxx RJ45 etc.

Trying to find a component? I was wondering if anyone had a model of this component.

The NS datasheet is poor at explaining this difference but at least one of the lm9217n-8 circuits using the has a v output with a 15v supply. I don’t even know if your version has this chip or not. If you find these calculators useful then why not download Electronics Assistant? You might have to use a lower voltage regulator, a low drop-out type or an LM daatsheet similar adjustable regulator set to around 20V or so.

Multisim and Ultiboard

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

Want to suggest a link to add here, exchange links with us or get a banner for your website? You need to experiment to see if this would work though ratasheet it’s not something I’ve had the need to try.

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 am designing a circuit in MultiSim and I am utilizing a LMN pin frequency to voltage converter as part of the circuit.

Lm29117n-8 1 of 3. I’ve hooked up an LM now to supply 20v as you suggested.

Is there any way of applying datasehet positive offset of say 0. Post any general technical questions here. I have not been able to find a model of this anywhere. Kittmaster’s Component Database http: Banana Used on test leads etc.

Message darasheet of 3. Most Active Software Boards: The rest would be relatively easy with ideal components. I had the idea to use an LMN-8 frequency to voltage converter and after reading through the data knocked up a circuit.

Do I need a transistor amplifier? Remember that the drop-out voltage of a standard 78x regulator is V, so a probably won’t work. Click here for details. Thanks for any help. A simple lm297n-8 is easy to make, however, the simulation file s are much more complicated and I datasheey not have to know how to do this.

The charge pump would be problematic without more detail about it’s internal construction. Thanks for the info.
