Hi, what is the frequency bandwidth lock the LM567 can achieve? I.e if it has been set to lock to 700Hz, will it lock on 710Hz as well or 701Hz or 700.001Hz or what?

Hi,

700Hz? Just to be sure, please confirm that this is a typo.

Thanks a lot!
A rough estimation on this circuit? Just to get an idea.
I want to use it as a "zero-beat" indicator, but my zero won't be 0hz but actually 700Hz or so.

Use the equations in the datasheet link I posted or the application manual, and
this calculator to get your designed tuned -


You have not mentioned your design criteria, like BW desired, signal environment like
adjacent tone rejection, T and V stability.....

Note care in choosing capacitors, depending on type and technology they can be very
T and V sensitive.


Regards, Dana.
