Part Number: LM2917-N RE LM2917/ LM2907
I am looking to use a series of these IC's on a turbine project to trigger multiple relays from multiple circuits at intervals of increasing turbine speeds
Hz will range from 30 - 180. The voltage from the sensor…
Part Number: LM2917-N Hello.
We have a variable reluctance sensor that we would like to buffer to a TTL or other voltage level. The LM2907/2917 seems like a good candidate. On page 20 of the datasheet, figure 28 a circuit is described that outputs pulses…
Part Number: LM2917-N THIMC,
I want to convert a PWM signal (14Vpp dc, duty Cycle 50%, 4kHz to 8kHz) into a PLC conform Signal 0-10V with the above mentioned F/V converter LM2917-N.
What are the resistor and Cap values? Maybe an OPAmp for the…
Part Number: LM2907-N Hi,
I need a s implified interpretation form which is written in the datasheet.
What is the role of the zener?
Best regards,

Other Parts Discussed in Thread: LM2917-N , LM2907-N My customer is planning to use LM2917-N. Could you tell us the following information ?
1) What is the recommended operating range for Supply Voltage, MIN and MAX ?
2) What is the accuracy (linearity…
The datasheet states it can sink 50mA and the electrical characteristics table has a min of 40, typical of 50mA, but no max value.
Would it be possible to find out the max value or if I could sink 80-90mA?
Thank you
Part Number: LM331 Other Parts Discussed in Thread: LM2917-N , Hi team,
The customer needs to select a voltage-to-Frequency converter. His requirements are as below:
1. The power supply is 12V.
2. Convert 0~10KHZ to 0~10V.
The customer would like…
Hi Eddie,
I've tried to determine what each stage is doing in the schematic, and I am not totally sure what you had in mind regarding their operation. Can you describe your expectations of their operation, with and without light flicker, and what each…
Hello Madu,
See the datasheet for the LM2907/LM2917 voltage-to-frequency converter:
There is an applications note that may prove helpful:
