The input signal must therefore go positive AND negative for the circuit to work.

National Semiconductor

Don’t worry about calculating the R1,C1,C2 values. 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.

Welcome to our site! Datasheets, Manuals or Parts. Or any other lm9207n can achieve the task? This feature allows either a ground or supply referred load of up to 50 mA. Now I understand the chip gives dataeheet a 0volts to Vcc variation for 0 Hz to fmax.

For a better experience, please enable JavaScript in your browser before proceeding. Also, I need to be very conservative wrt adding components. Articles Top Articles Search resources.

As I want to know the attached circuit is correct as what you mention? Any suggestions on how to implement that? As i read from d’sheet it can’t do this. Both of these configurations are available with an active. You can then drive the transistor to give you an output of up to Vcc.

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. Thank you for your reply. 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.

Replacement Transformer Started by ncag 47 minutes ago Replies: Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at The two basic configurations offered include an 8-pin device with a ground referenced tachometer input and an internal connection between the tachometer output and the op amp non-inverting input.

But i want to know the accuracy of this circuit? Sebi Active Member Jul 2, National Semiconductor Electronic Components Datasheet. That range can give me a larger range to have a more accuracy signal to do speed control. This version is well suited for single speed or frequency switching or fully buffered frequency to voltage conversion applications.

The more versatile configurations provide lm9207n ta. Klaus New Member Jul 3, It only can be varying within V output for 40Hz input.

With this version the tachometer input may be floated and the op amp becomes suitable for active filter conditioning of the tachom- eter output.

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 datasneet pump will go high, being low at all other times.

I am before use the below circuit and it work. Frequency to Voltage Converter. Thank you a lot. LM, LM and its output swings to ground for a.

I don’t know why. Click here to register now. I have made the circuit but seem not work.

Other than that you said the circuit worked, just gave the wrong rangethe diagram you posted is correct, the vaues should be OK. Thank you very much. Sorry, can you give me any advice of which type can do datasyeet thing?
