LM2907N DATASHEET PDF

The input signal must therefore go positive AND negative for the circuit to work. Welcome to our site! Datasheets, Manuals or Parts. Or any other lmn 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.

Tutaur Or any other methods can achieve the task? 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. To do better requires more info — supply voltage, rest of circuit components?

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. 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. You can then drive the transistor to give you an output of up to Vcc. Frequency to Voltage Converter. The two basic configurations offered include an 8-pin device. 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?
