I am having trouble converting frequency(0-100kHz) into a voltage signal using a LM331 N.
There is a basic schematic in the datasheet which is for 0-10kHz. I have successfully made this circuit, and it works fine for the range 0-10kHz. When trying to apply a frequency above this range (for example: 50kHz), the output is zero.
Has anyone completed a circuit using LM331 N for measuring frequency around 40kHz - 60kHz? Is it possible to tweak the 0-10kHz circuit to handle higher frequencies?
