So, each valley is about 66 microSeconds apart at 15kHz.


Many of these devices are operated by non-tech-savvy users who may not know l2m58d to maintain their own device security. Nov 23, 8, 6, Can anyone tell me why the waveform is lean towards the back? The datasheet says the slew rate is 0.

Quote of the day.

can anyone tell me why the waveform come out like this way not dc voltage

I have an original circuits as follows: Can anyone tell me l2m58d this cable assy is for? Feb 18, 4. View attachment Figure 4 Modified circuit Here is the modified circuit output, which is not my expectation.


View attachment Figure km258d flyback circuit provides power input for the circuit in Figure 2 When I measured the pin 7 output at its original circuit in Figure 1, its output is dc voltage around That means 13 microSeconds going down and 13 microseconds going up.

Feb 16, 3. Thank you for your help.

You need a slower Pwm frequency or a faster op amp. Feb 16, 1. Do you already have an account?

Also, what is the function of Q2 in this circuit? Datashedt 1, 7, 2, Yes, my password is: The output was as follows. That means, according to my calibrated eye, the valley is about 25 microsecond wide.

Why did you replace an emitter-follower pull up device with a 47K resistor? This is a very large increase in output impedance, and introduces a phase shift and low pass filter into the second opamp’s feedback loop. Digital Signal Processing in Scilab: Posted by Faizan Ahmad in forum: Posted by sarkarnov in forum: Feb 16, 2. How does this happen? You May Also Like: So, let’s take 13 microseconds 0.


I don’t know if this saturated and the top was datasueet since this is very big output gain. Note that low power devices are usually slow speed devices.

Looking at your o-scope output, my calibrated eye is fairly accurate and the datasheet is exactly right.

View attachment Why does its output perform like this way, not dc voltage output? After I modified the circuits, which Q1 was replaced with 47K resistor and I put diode between pin 7 and the base of Q3.
