Kato-san,
The LM2917-N can be RC coupled as you have shown. The RC circuit provides a differentiator function right before the LM2917-N input. The high/low transistor output transitions will be differentiated and produce negative and positive spikes…
Part Number: LM2917-N Other Parts Discussed in Thread: NE555 , LM231 Hi .... Please forgive my bad language, I'm from Indonesia and still studying in electronics I plan to make a Vehicle Speed Limiter for Common-rail Truck with LM2917N-14. The input signal…
Part Number: LM2917-N Hi,
Could you please provide the measurement data for FV curve when configuring the the following frequency to voltage converter with LM2917M-8/NOPB? Additionally, according to the following application note, is my understanding…
Part Number: LM2917-N
The datasheet says the response time of the LM2917 is set by C2, but I cannot find an equation that relates response time to C2
In the lab, with a 1uF value for C2, I measure a response time of apx 500ms.
I see an equation…
Part Number: LM2917-N Hi,
Is my understanding correct that an independent power supply voltage can be supplied to the collector pin(5 pin) as follows if using LM2917M-8/NOPB with the zener regulated frequency to voltage converter? Additionally, please…
Mehmet, It looks like your LM2917-N E2E inquiry may have been overlooked during a transfer of products between TI internal divisions. If that happened we apologize.
Did you ever get the LM2917-N circuit working? If not, what did you observe about its…
Part Number: LM2917-N I am using the LM2907 in a frequency to voltage configuration. My input power supply varies from 23-26V, and it is causing too large of a swing in my output voltage.
I have decided to switch to the LM2917 part instead with the…
Part Number: LM2917-N I intend to use the device to interface a magnetic pickup to an ignition controller. The input pulse peaks will most likely exceed 100V or so at higher engine speeds. Does the chip have the capability to adjust threshold or is there…
