A Reasonable Facsimile??

Greetings,

The LM331 chip is/was used in a V to F circuit I found but, as I understand
it, the chip was discontinued in 1995. Is there a sub that can be used?

The circuit can be viewed at:

It is the frequency to voltage circuit that allows the frequency to be read
as voltage with a DVM.

Thanks,
Randy
