Part Number: LM331 Other Parts Discussed in Thread: VFC320
Hi team
My customer is seeking replacement solution for AD7740KRM.
I am looking at LM331 V-F converter, however, the maximum output frequency only 100Khz of this device.
Do we have new…
Part Number: LM331 Hi team,
My customer is using LM331 to convert a input voltage to square wave output. The schematic is as below:
AIin is the input to LM331 and Fout is the output of LM331. We found that when AIin is connected to GND, Fout waveform…
Part Number: LM331 Hi,
Because there is not a good simulation model for the LM331 therefore my question: Is there a spreadsheet where you can have as input the Vs, Rt, Ct, Rs, Rl, Cl, max input frequency. What will give value/graphic a max output voltage…
Hello Bavo,
The LM331 utilizes an internal one-shot timer to provide the pulse output which doesn't support maintaining a constant 50 % duty cycle over an assigned V-to-F range.
The optional offset control circuit applied in the LM331 datasheet Fig…
Part Number: LM331 Other Parts Discussed in Thread: LM231 Hi,
we are using a circuit that include an LM331. The LM331 is in a circuit reproducing the basic Voltage tot Frequency converter of Figure 14 in the datasheet.
That circuit was used at a temperature…
Part Number: LM331 Hi all,
My customer would like to use this with frequencies as low as 0 to 4Hz at the input for the frequency to voltage conversion. Using the equations for Vout in Fig 18, they're trying to figure out what values of RL and RS to…
Part Number: LM331 Hello，
Do we have the simulation model like TINA of LM331 or other FV conversion devices? Our customer hope we could provide it for simulation.
Best regards

Part Number: LM331 I am trying to debug 50 boards that are implementing the LM331 as a voltage to frequency converter. My desired frequency is 3.9 kHz. On 10 of the boards the frequency is within +/- 2kHz which is okay for my application. However on the…

Dear ,
I did LM331 board as expected, but I have a strange signal output which is coming worst with voltage increasing :
any idea ?
Best regards
Hello Ashay,
We don't have any additional information about the LM331 application circuit shown in Figure 14. It does state in the design requirments that the available supply voltage is 15 V, and an input voltage range of 25 mV, to 12.5 V. It may be…
