Thought that ttoo. I quest more people are intrested in more practical Electronics. This lady is amazing. Very special.

more than a wonderful LM331 video.. i have a LC v2F module can generate different frequency with no schematic and before i let the smoke out i better see how to hook up the output....? Two independent outputs, OC-OUT is NPN, and FREQ-OUT is IC output. The common cathode end is matched with the negative GND of the power supply. When common anode connects, it is used with power positive. If the connection is common anode and power supply is 13-24V, please serial connect a 2.7K ohm resistor; if the power supply is 12V, please serial connect a 330 ohm resistor. Connect the frequency pulse signal to F, and there is a corresponding voltage output at the terminal. Correspondence between input and output: 1V=1KHZ 10V=10KHZ. If there is a deviation, you can adjust the potentiometer on the board to calibrate. thanks a lot, your video will help...:) input: 0-10V output: 0-10KHz Operating Voltage: 13.5V-30V

That's one hell of a schematic!

The TLS230 chip, molded in a clear body, performs this same function.

Do you know where I can buy TLS230R ? I can't find on Amazon.

I feel like that circuit needs to be nicknamed a "phototheremin" :D

can you help to build frequency up to 800 mhz to voltage circuit?

What is the difference between "voltage to frequency converters(VFC)" and "Voltage controlled oscillator (VCO)"?

I have a project idea involving the LM331. Unfortunately, it's taking MONTHS to arrive from China. Can't we order them from Texas or somewhere?

what is output waveform of V/F LM 331 ? is it sine wave?
@topquark22 4 жыл бұрын
No, it's a square wave.
