f to v circuit

Please give me circuit diagram of Frequency to Voltage converter. IC 9400 is not available so please give me circuit diagrams using other ICs. Frequecy is 1 to 10KHz.

Thanks,


Sangmeshwar

f/v circuit

Monostable multivibrator output when averaged is F to V converter.

f to v converter circuit diagram

find the datasheet of ADVFC32 IC from analog devices(www.analog.com) ,This IC is F/V and V/F converter.

There are sch in datasheet.

Hi,

I accidentally found this circuit in an old magazine, I hope that your
Dutch is as fluent as mine.

f to v convertor ic

you can also implement an F-V functionality using microcontroller.

Hi.
I used in the past LM2907 and work fine. Also some industrial F/V converters use this. Better for some boards is to use one H11L1 optocoupler, if the frequency is high.

Regards, even if is a late answer...
