Replacement Transformer Started by ncag 47 minutes ago Replies: As I want to know the attached circuit is correct as what you mention? Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Sorry, can you give me any advice of which type can do such thing? Datasheets, Manuals or Parts. Forums New posts Search forums. The tachom- eter uses a charge pump technique and offers frequency doubling for low ripple, full input protection in two versions LM, LM and its output swings to ground for a zero frequency input.

To participate you need to register. Media New media New comments Search media. Both of these configurations are available with an active shunt regulator connected across the power leads. Stick with the LM I’m sure the LM is capable of doing what you want, it just needs some component changes to set the range. The two basic configurations offered include an 8-pin device.


Also, the ripple of the output will affect the output range or not? Potentiometer Questions Started by norbss Yesterday at Don’t worry about calculating the R1,C1,C2 values. Adding 2 more ics datasheft do the trick is not an option. I’m trying to sense the freq of a square wave from 10KHz – 40KHz range. Thank you very much. Both of these configurations are available with an active. With this version the tachometer input may be floated and the op amp becomes suitable for active filter conditioning of the tachom- eter output.

You must log in or register to reply here. But I lmm2907n cannot be sucessful to make a larger voltage output range. Now I understand the chip gives you a 0volts to Vcc variation for 0 Hz to fmax. I have followed the datasheet of LMN to design datasheett frequency to voltage circuit.

By continuing to use this site, you are consenting to our use of cookies. The two basic configurations offered include an 8-pin device with a ground referenced tachometer input and an internal connection between the tachometer output llm2907n the op amp non-inverting input.

Other than that you said the circuit worked, just gave the wrong rangethe diagram you posted is correct, the vaues should be OK. LM, LM and its output swings to ground for a.


Thank you a lot. Frequency to Voltage Converter.

LM2907N Datasheet PDF

I have made the circuit but seem not work. But I need 10khz to 40khz give me a 0 volt – Vcc variation.

For a datasheeet experience, please enable JavaScript in your browser before proceeding. I don’t know why. The more versatile configurations provide differential ta- chometer input and uncommitted op amp inputs. The LM, LM series are monolithic frequency to. Also, I need to be very conservative wrt adding components.

National Semiconductor Electronic Components Datasheet. This version is well suited for single datasjeet or frequency switching or fully buffered frequency to voltage conversion applications.

This op-amp works as a sort of ‘trip amp’, whenever the input on pin 1 exceeds the voltage on pin 8 0vthe output to the charge pump will go high, being low at all other times. Click here to register now.

It only can be varying within V output for 40Hz input. Welcome to our site!
