Hi, i need a voltage controlled oscillator and reading in my textbook there is an example how to make one using a frequency to voltage converter. They use a LM331 IC and i have attached the circuit the textbook shows.
I have a LM2907 frequency to voltage converter and would like to use this instead of the LM331 (which i dont have). (The LM2907 datasheet doesnt have a VCO example so i cant follow that) Is it ok to use this instead of the LM311 in its circuit?
Assuming it is, i'm unsure of what pins on the LM2907 correspond to the pins on the LM331 VCO circuit.
I have the 14 pin LM2907N
My guess so far at the pins are:
LM331 pins = LM2907 pins
1 3
2 11
3 5
4 12
5 4
6 2
7 10
8 8
To be honest these really are just guesses, i don't understand the workings of either the LM331 or LM2907 sufficiently to make a proper guess and suspect i can't use the LM2907 to replace the LM331.
Any help would be appreciated
