LM331 PDF

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.

But I’m getting 5V constant output when I use 5V supply. This will give you a square wave at half the frequency.

LM331 Frequency to Voltage Converter Circuit

The LM works by putting out fixed-width pulses and there is nothing you can do to change this. You lm3331, however, follow the with a divide by 2 circuit, using something pm331 a 74HC Since LM works at 5V supply, I can scale 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. How can I modify this circuit so I can run the simulation for 5V supply?

I followed the instructions to use LM in LTspice and simulated the circuit below: From page 4, 7.

What else sets what here?

LM Frequency to Voltage Converter Circuit

Post as a guest Name. Do you think this circuit is correct?

Yes so I can use it with 12V supply as well then since Vs is max 40V. I came across this circuit and this forum. And are the values of components dependent on supply voltage?

LM Voltage to Frequency Converter Circuit

Yes sure, I tried 1V 0. LM should work with 5V supply.

I’m trying to convert I mean C1 and R1 sets the frequency but thats all I know. Sign up using Facebook. It works when I use 10V supply. If the actual labels are 1 and 5then you may wish to change the directive to.
