Part Number: LM2917-N Other Parts Discussed in Thread: LM2907-N Hello,
Could anyone provide the tolerance of LM2917-N internal Zener diode?
My customer using 12V supply and 470ohm resistor. However the regulated voltage is around 7.9V at room temperature…
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 correct…
Hi William,
in opposite to the LM2907-N, the LM2917-N has an internal 7.5V zener diode connected from pin 6 (V+) to pin 8 (GND). Have a look at section 9.2 of datasheet. And when you connect a +15V supply voltage to V+ you will barbecue this internal…
Hello Bhautik and Karun,
Paul has provided good reference information regarding the use of a comparator as a zero cross detector. The frequency-to-voltage (F-V) conversion might be accomplished by an LM2907-N or LM2917-N F-V converter, or the LM331 V-F converter…
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 internally…
Part Number: LM2904-Q1 Other Parts Discussed in Thread: LM2904-N Hi team
My customer asked input current of Absolute maximum ratings.
For the LM2907, the Absolute maximum input current displays 50mA as shown below.
But, I don't find Absolute maximum…
Hello Mathan,
Connect the sensor as you have it now (GND to GND, + to supply), but place a 0.1uF in series (between) the sensor output "SIG" and the LM2907 pin 1.
The capacitor blocks the DC component and passes the AC component. The voltage…
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…
Other Parts Discussed in Thread: LM2907-N Hello everyone. I am using the LM2907 for a speed switch application (figure 20). I have for my load a 10k resistor connected to 5V, which is my vcc. For my input signal, I am using the square pulses from the function…
