10 x LM331N LM331 ic DIP-8

so this lm3 3-1 chip we have is actually specific to the task of converting voltage to frequency a voltage to frequency converter like this is actually pretty useful for applications that need to sense really weak signals that that don't change very quickly because you can convert the voltage to a frequency and then kind of count pulses and integrate that over a period of time so I've found circuits like this inside of digital scale I've used circuits like this in the past for making kind of spectrometer equipment it's a pretty nice way of getting kind of arbitrary precision analog to digital conversion here's the pin out I've got a frequency output this wide dynamic range is actually one reason you'll see people use a voltage to frequency converter instead of a traditional A to D since with the same electronics you can sense very different levels of signal intensity by adjusting your i
