LM331 PDF

December 17, 2018

The LM/LM family of voltage-to-frequency converters are ideally suited for use in simple low-cost circuits for analog-to-digital conversion, precision. Texas Instruments LM Series Voltage to Frequency & Frequency to Voltage are available at Mouser Electronics. Mouser offers inventory, pricing. A Voltage to Frequency (VTF) converter is a circuit, which converts a voltage level to a linearly proportional frequency. A special configuration of the LM IC.

What is that poti for? Post as a guest Name. I mean C1 and R1 sets the frequency but thats all I know.

How can I modify this circuit so I can run the simulation for 5V supply? Sign up using Facebook. From page 4, 7.

Since LM works at 5V supply, I can ml331 Post Your Answer Discard By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is ln331 to these policies. I came across this circuit and this forum. The LM works by putting out fixed-width pulses and there is nothing you can do to change this.

I’m trying to convert While Vs at lm331, did u ensure that your input does not cross 5V? You can, however, follow the with a divide by 2 circuit, using something like a 74HC This will give you a square wave at half the frequency. Yes so I can use it with 12V supply as well then since Vs is max 40V.

Do you think this circuit is correct? But in simulation with 5V it doesn’t work. But on the on the other hand, on the first page it says “Operates on Single 5-V Supply” But it doesnt work at 5V supply in simulation.

And are the values of components dependent on supply voltage? What else sets what here? It works when I use 10V supply.
