Original question:

LM2917-N: LM2917-N

LM2917-N: lm2917

Part Number: LM2917-N

I'm using the LM2917 in 14 pins package, I can't make it work, maybe you can draw me the correct schematics for a pulse from 0 to 2.3Khz 0-5v 

that I would lkie to measure using a 3.3V A2D, I'm currently using 24V as input voltage 

Thank 

Shai

    Hello Shai,

    I am directing you to an Application Note for the LM2907/LM2917. Make sure you apply the 14-pin, LM2917N pinout shown in Figure 1. 

    https://www.ti.com/lit/an/snaa088/snaa088.pdf

    Then, follow the information starting on Page 4 "HOW TO USE IT." Between the information provided in the by the datasheet and the Applications Note you should be able to figure out to set the R1, C1 and C2 values for a 0 to 3.2 kHz, 5 V maximum output.

    Regards, Thomas
