Or any other methods can achieve the task? I’m trying to sense the lm22907n of a square wave from 10KHz – 40KHz range. The regulator clamps the supply such that stable frequency to voltage and frequency to current operations are possible with any supply voltage and a suitable resistor.

As I want to know the attached circuit is correct as what you mention? To do better requires more info – supply voltage, rest of circuit components? Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.

The IC has three basic sections, a trip amp, a charge pump and an op amp, if the charge pump and following integrator can’t be set to the desired time constant then the op amp can give lots of gain.

Any suggestions on how to implement that? By continuing to use this site, you are consenting to our use of cookies. So, can you give me any advice about the accuracy of the circuit?

The more versatile configurations provide differential ta. With this version the tachometer input may be floated and the op amp becomes suitable for active filter conditioning of the tachom- eter output. Thank you a lot. Thank you for your reply.

Other than that you said the circuit worked, just gave the wrong rangethe diagram you posted is correct, the vaues should be OK.

Sorry, can anybody give me advice or the circuit is correct or any incorrect place?

It only can be varying within V output for 40Hz input. But I still cannot be datasehet to make a larger voltage output range.

Replacing a 4 pin leaded inductor with datasheett 2 pin Started by gkmaia Yesterday at Adding 2 more ics to do the trick is not an option. LM – 8 pin package As you show the 8 pin package circuit, I assume this is what you have – there is a 14 pin version as well. I have made the circuit but seem not work. 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 lm297n charge pump will go high, being low at all other times.


You can then drive the transistor to give you an output of up to Vcc.

Thank you very much. The 8 pin package has the op-amp input stage’s inverting input connected to ground via pin 8the non-inverting input is on pin 1. Frequency to Voltage Converter. The two basic configurations offered include an 8-pin device.

I don’t know why. This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register. I have followed the datasheet of LMN to design a frequency to voltage circuit.

But i want to know the accuracy of this circuit? Sorry, can you give me any advice of which type can do such thing? Media New media New comments Search media. I am before use the below circuit and it work.
