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.

I followed the instructions to use LM in LTspice and simulated the circuit below: How can I modify this circuit so I can run the simulation for 5V supply? I mean C1 and R1 sets the frequency but thats all I know. Home Questions Tags Users Unanswered. But in ln331 with 5V it doesn’t work. From page 4, 7.

The LM works by putting out fixed-width pulses and there is nothing you can do to change this.

It works when I use 10V supply. Yes sure, I tried 1V 0.

I came across this circuit and this forum. What is that poti for?

This will give you a square wave at half the frequency. WhatRoughBeast Do you think the circuit in my simulation is correct? LM should work with 5V supply.

Since LM works at 5V supply, I can scale And are the values of components dependent on supply voltage? But on the on the other hand, on the first pm331 it says “Operates on Single 5-V Supply” But it doesnt work at 5V supply in simulation. But I’m getting 5V constant output when I use 5V supply.

I’m trying to convert Can someone explain me how this circuit works?
